Symfony 3.x : form with 1-N-1

I am trying to create a form for a media with a sub collection of tags. Following doctrine documentation I create that :

Test\CommonBundle\Entity\Media:
    type: entity
    table: media
    repositoryClass: Test\CommonBundle\Repository\MediaRepository
    indexes:
        index_title:
            columns: [ 'title' ]
    fields:
        id:
            type: integer
            id: true
            generator: { strategy: IDENTITY }
            nullable: false
        title:
            type: string
            nullable: false
            length: 200
    oneToMany:
        tagAssociate:
            targetEntity: Test\CommonBundle\Entity\TagAssociateMedia
            mappedBy: targetAssociate

Test\CommonBundle\Entity\TagAssociateMedia:
    type: entity
    table: tag_associate_media
    repositoryClass: Test\CommonBundle\Repository\TagAssociateMediaRepository
    fields:
        createdAt:
            type: datetime
            nullable: true
    manyToOne:
        targetAssociate:
            targetEntity: Test\CommonBundle\Entity\Media
            inversedBy: tagAssociate
            joinColumn:
                name: target_id
                referencedColumnName: id
        tag:
            targetEntity: Test\CommonBundle\Entity\TagMedia
            inversedBy: tagAssociate
            joinColumn:
                name: tag_id
                referencedColumnName: id

Test\CommonBundle\Entity\TagMedia:
    type: entity
    table: tag_media
    repositoryClass: Test\CommonBundle\Repository\TagMediaRepository
    indexes:
        index_name:
            columns: [ 'name' ]
    fields:
        id:
            type: integer
            id: true
            generator: { strategy: IDENTITY }
            nullable: false
        name:
            type: string
            nullable: false
            length: 100
    oneToMany:
        tagAssociate:
            targetEntity: Test\CommonBundle\Entity\TagAssociateMedia
            mappedBy: tag

I create entities. For exemple I have for Media :

<?php
namespace Test\CommonBundle\Entity;

use Doctrine\Common\Collections\ArrayCollection;

use \Test\CommonBundle\Entity\TagAssociate;

/**
* Media
*/
class Media
{
    /**
     * @var integer
     */
    protected $id;

    /**
     * @var string
     */
    protected $title;

    /**
     * @var \Doctrine\Common\Collections\Collection
     */
    protected $tagAssociate;

    /**
     * Constructor
     */
    public function __construct()
    {
        $this->tagAssociate = new ArrayCollection();
    }

    /**
     * Get id
     *
     * @return integer
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set title
     *
     * @param string $title
     *
     * @return Media
     */
    public function setTitle($title)
    {
        $this->title = $title;

        return $this;
    }

    /**
     * Get title
     *
     * @return string
     */
    public function getTitle()
    {
        return $this->title;
    }


    /**
     * Add tagAssociate
     *
     * @param \Test\CommonBundle\Entity\TagAssociate $tagAssociate
     *
     * @return Media
     */
    public function addTagAssociate(TagAssociate $tagAssociate)
    {
        $this->tagAssociate[] = $tagAssociate;

        $tagAssociate->setTargetAssociate($this);

        return $this;
    }

    /**
     * Remove tagAssociate
     *
     * @param \Test\CommonBundle\Entity\TagAssociate $tagAssociate
     */
    public function removeTagAssociate(TagAssociate $tagAssociate)
    {
        $this->tagAssociate->removeElement($tagAssociate);
    }

    /**
     * Get tagAssociate
     *
     * @return \Doctrine\Common\Collections\Collection
     */
    public function getTagAssociate()
    {
        return $this->tagAssociate;
    }
}

I create the TagMedia on the same model and create intermediate entity with $targetAssociate and $tag attributs and their getter/setter. Until now, I can manipulate my entities without problem.

Now the problem, I try to create a Form like this :

<?php
namespace Test\BackBundle\Entity\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\CollectionType;

use Symfony\Component\Form\FormInterface;

use Test\CommonBundle\Entity\Media;

class MediaType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options){
        $builder
            ->add('title', TextType::class, array(
                'label' => 'entity.media.title',
                'required' => true,
            ))
            ->add('tagAssociate', CollectionType::class, array(
                'label' => 'entity.tagAssociate',
                'required' => false,
                'entry_type' => TagAssociateType::class,
                'allow_add'    => true,
                'allow_delete' => true,
            ))
        ;

    }

    public function configureOptions(OptionsResolver $resolver){
        $resolver->setDefaults(array(
            'data_class' => Media::class,
            'translation_domain' => 'messages',
            'validation_groups' => function (FormInterface $form) {
                $data = $form->getData();
                $id = $data->getId();

                if( $id ){
                    return array('update');
                }

                return array('Default');
            },
        ));
    }

    public function getName(){
        return 'test_back_type_media';
    }
}

and the sub Form :

<?php
namespace Test\BackBundle\Entity\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

use Symfony\Component\Form\FormInterface;

use Test\CommonBundle\Entity\TagAssociateMedia;

class TagAssociateType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options){
        $builder
            // what i am suppose to add here ?
            ->add('tag', EntityType::class, array(
                'class' => TagMedia::class,
                'label' => 'entity.tag',
                'required' => false,
                'choice_label' => 'name',
            ))
        ;
    }

    public function configureOptions(OptionsResolver $resolver){
        $resolver->setDefaults(array(
            'data_class' => TagAssociateMedia::class,
            'translation_domain' => 'messages',
            'validation_groups' => function (FormInterface $form) {
                $data = $form->getData();
                $id = $data->getId();

                if( $id ){
                    return array('update');
                }

                return array('Default');
            },
        ));
    }

    public function getName(){
        return 'test_back_type_tag_associate';
    }
}

With that, I don't have error and I have 0 and 1 display (in twig with {{ form_row(form.tagAssociate) }}) when I have 2 ligns in the relation as in this screen :

But my problem come when I want to have this : I want to have a list of checkbox corresponding to the relation and when I uncheck, on the update, this relation will be remove (I will manage in JS to add new relation with prototype and ajax request to ask server about available tags).

Any idea how I can do ?
