How to connect elfinder and tinymce in symfony2?

Question

symfony

Hello, please tell me where I am making a mistake. I'm trying to connect Eldinder and Tinymce to edit and upload images while creating articles.
Here is ArticleType

class ArticleType extends AbstractType
{

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name', 'text')
                ->add('text', 'textarea', ['attr' => ['class' => 'tinymce', 'data-theme' => 'advanced']])
                ->add('save', 'submit');
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'App\MainBundle\Entity\Article',
        ));
    }

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

}

But the editor still does not appear.

Bundle resources installed?
Are they included in the template?
