Source button

Hello, I'm using h5p drupal7 module and I was trying to add extra plugin sourcedialog to the CKEditor toolbar using the guide provided here, but wasn't successful. In fact plugin was loading, but was never assigning to the actual toolbar. Maybe you can give me any clue why isn't that working for me? The source code is:

function mymodule_h5p_semantics_alter(&$semantics, $library_name = NULL) {
  // Check if this is the multichoice question type.
  if ($library_name !== 'H5P.CoursePresentation') {
    return; // Nope, do not continue.
  }

  foreach ($semantics as $field) {
    // Go through list fields
    while ($field->type === 'list') {
      $field = $field->field;
    }

    // Go through group fields
    if ($field->type === 'group') {
      mymodule_h5p_semantics_alter($field->fields, $library_name);
      continue;
    }

    // Check to see if we have the correct type and widget
    if ($field->type === 'text' && isset($field->widget) && $field->widget === 'html') {
      // Found a field. Add support for table tags.
      if (!isset($field->tags)) {
        $field->tags = array();
      }
      $field->tags = array_merge($field->tags, array(
        'sourcedialog',
      ));
    }
  }
}

function mymodule_form_h5p_content_node_form_alter(&$form, &$form_state) {
  $module_path = drupal_get_path('module', 'mymodule');
  $cache_buster = '?' . variable_get('css_js_query_string', '');
  $form['#attached']['js'][] = array(
    'data' => array(
      'h5peditor' => array(
        'testPath' => base_path() . $module_path . '/',
        'assets' => array(
          'js' => array(
            '/' . $module_path . '/extraplugins.js' . $cache_buster
          )
        )
      ),
    ),
    'type' => 'setting',
  );
}

var H5PEditor = H5PEditor || {};
H5PEditor.HtmlAddons = H5PEditor.HtmlAddons || {};
H5PEditor.HtmlAddons.sourcedialog = H5PEditor.HtmlAddons.sourcedialog || {};
H5PEditor.HtmlAddons.sourcedialog.sourcedialog = function (config, tags) {
    config.extraPlugins = (config.extraPlugins ? ',' : '') + 'sourcedialog';
    config.toolbar.push({
        name: "sourcedialog",
        items: ['Source']
    });
console.log(config);
    tags.push('sourcedialog');
};
  
(function ($) {
    $(document).ready(function () {
        if (window.Drupal === undefined) {
            window.Drupal = window.top.Drupal;
        }
        if (window.CKEDITOR !== undefined) {
            // Add plugin
            ['dialog', 'sourcedialog'].forEach(function (p) {
                CKEDITOR.plugins.addExternal(p, Drupal.settings.h5peditor.testPath + p + '/');
            });
        }
    });
})(H5P.jQuery);
