wp_editor modalbox width backbone

Hello,

I’m working on a plugin that need to use the text editor in some modal box. I am using backbone.

When backbone renders the view in which the text editor is included, it doesn’t work. The tabs don’t work and the buttons doesn’t appear.

Example:

class Modal {

  public function __construct( ) {
    if ( is_admin() ) {
      add_action( 'admin_footer', [ $this, '_render_template' ] );
      add_action( 'admin_enqueue_scripts', [ $this, '_admin_enqueue' ] );
    }
  }

  public function _render_template() {
    echo '<script type="text/template" id="tmpl-modal">';
      wp_editor( 'Text...', 'modal-box-editor' );
    echo '</script>';
  }

  public function _admin_enqueue( $hook ) {
    if ( 'post.php' != $hook && 'post-new.php' != $hook ) return;
    wp_enqueue_script( 'modal-box-script', get_template_directory_uri() . '/modal-box-script.js', [ 'jquery', 'backbone', 'underscore' ], null, true );
  }
}

$Modal = new Modal();

Javascript:

jQuery(document).ready(function($) {

  ModalView = Backbone.View.extend({
    tagName : 'div',
    template : _.template( $( '#tmpl-modal' ).html() ),
    $parent : $( 'body' ),

    initialize : function() {
      this.render();
    },
    render : function() {
      this.$el.html( this.template() );
      this.$parent.append( this.el );
      return this;
    },
  });
  var ModalBox = new ModalView();
});

Can someone help me?

Thank You
