Needs to destory existing editor instance before creating a new one.

[danieliser]

Just inside of this.each function you should be calling something like:

            if(tinyMCE.editors[current_id] !== undefined) {
                tinyMCE.remove(tinymce.editors[current_id]);
            }

This clears any previously rendered version.

This is important if your rendering the forms on the fly everytime, but with the same ids.
