[Moo] problem whith mousewheel event

[hartum]

Hi again everybody

I am developing a custom scrollbar (nothing new under the sun), but I
can not make "mousewheel" event work.
Here is the code:

http://jsfiddle.net/XFxu2/1/

look at line 27, of js:

 self.content.addEvent('mousewheel', function(event){
            console.log('scrolleando');
  });

Could you help me please? Thank you very much

p.d: sorry for my english
