Can't bind on events in a plugin that extends sortable

[NiGhTTraX]

I'm trying to build a plugin that extends sortable and in the _create method of my plugin I'm calling _super() . After that I try to bind on some sort events, but it doesn't seem to work, my handlers don't get triggered.

See this for more details ​http://jsfiddle.net/NiGhTTraX/ArT7M/

If instead of calling _super() I manually create the sortable on that.element everything works.

Seems that someone else is having this problem too ​http://forum.jquery.com/topic/to-extend-or-wrap#14737000000967254

That's because the widget instance is not a sortable instance, it's a myplugin instance. There is no polymorphism in the widget factory.
