Programmatically created attribute appears in database, but not in Magento back-end

Question

In a new Magento extension, I'm creating some custom product attributes.
But when I'm testing the extension, the attributes doesn't appears in the back-end. When I'm looking in the database, then I see that the attributes are created...

Is it possible I'm forgetting something in my Setup.php?

That's my code: /Model/Resource/Eav/Setup.php

/**
 * @return array
 * An array with product entities: medipim_version
 */
public function getDefaultEntities()
{

    /*$setup = new Mage_Eav_Model_Entity_Setup('core_setup');
    $setup->removeAttribute('catalog_product','medipim_version');*/
    //
    return array(
        'catalog_product' => array(
            'entity_model'                  =>  'catalog/product',
            'attribute_model'               =>  'catalog/resource_eav_attribute',
            'table'                         =>  'catalog/product',
            'additional_attribute_tabel'    =>  'catalog/eav_attribute',
            'entity_attribute_collection'   =>  'catalog/product_attribute_collection',
            'attributes'    => array(
                'medipim_version' => array(
                    'group'                             =>  'Medipim data',
                    'label'                             =>  'Version',
