Froala add custom pre code button

问题

I'm trying to create a code button with the Froala editor which can basicly do the same thing as here on SO by pressing CNTRL+K. Now I think I have two choices.

The first one is to edit the froala-editor.js file, because Froala already has a 'code' button which only adds the <pre> tags. If I could somehow get it to also add the <code> tag, problem solved. Unfortunately I didn't get this to work.

The second option is to create a custom button, so far I have this piece of code:

$('textarea[name="description"]').editable({
    //Settings here
    customButtons: {
        insertCode: {
            title: 'Insert code',
            icon: {
                type: 'font',
                value: 'fa fa-code'
            },
            callback: function() {
                this.saveSelection();

                if (!this.selectionInEditor()) {
                    this.$element.focus(); // Focus on editor if it's not.
                }

                var html = '<pre><code>' + this.text() + ' </code></pre>';

                this.restoreSelection();
                this.insertHTML(html);
                this.saveUndoStep();
            }
        }
    }
});

It works somehow, but it's buggy and produces strange html like so:

<p><code></code>
  <pre><code>asdasdasdasd
</code></pre>
</p>

Any help with getting this done for either option one or two would be greatly appreciated.

If you upgrade to version 1.2.3 that is available on Github your code should work https://github.com/froala/wysiwyg-editor. It's not necessary to save/restore selection.

LATER EDIT: Here is a jsFiddle for it http://jsfiddle.net/9pmmg1jk/.

customButtons: {
  insertCode: {
    title: 'Insert code',
      icon: {
        type: 'font',
          value: 'fa fa-code'
      },
        callback: function() {
          if (!this.selectionInEditor()) {
            this.$element.focus(); // Focus on editor if it's not.
          }

          var html = '<code>' + (this.text() || '&#8203;') + '<span class="f-marker" data-type="false" data-id="0" data-fr-verified="true"></span><span class="f-marker" data-type="true" data-id="0" data-fr-verified="true"></span></code>';

          this.insertHTML(html);
          this.restoreSelectionByMarkers();
          this.saveUndoStep();
        }
  }
}
