Symfony - buttonType - attribute with value from form entity

I was trying to build a form contains a button, which should have an attribute with baseId (eg. <button baseId="1">history</button>).

The problem is that baseId value should be get from entity for each row. I was trying as below:

public function buildForm(FormBuilderInterface $builder, array $options) {
            $builder
                ->add('bedsoreBaseId', ButtonType::class, ['attr' => [
                    'baseId' => function($entity) {
                    return $entity->getBaseId();
                }
                ], 'label' => 'history']);
}

However, this results in an error:

An exception has been thrown during the rendering of a template ("Catchable Fatal Error: Object of class Closure could not be converted to string").

What is the best way to access this property and use it as attribute value?

You can set it directly in template

{{ form_row(form.bedsoreBaseId, {'attr':{'baseId':form.vars.data.baseId }}) }}

Or add this element to form on PRE_SET_DATA event

public function buildForm(FormBuilderInterface $builder, array $options) {
    $builder->addEventListener(FormEvents::PRE_SET_DATA, function (FormEvent $event) {
            $data = $event->getData();
            $form = $event->getForm();

            $form->add('bedsoreBaseId', ButtonType::class, [
                'attr' => ['baseId' => $data->getBaseId()],
                'label' => 'history'
            ]);
        });
}
