Hi, can someone help me get the mousewheel working with my tree component?

I have this code - but it doesn’t seem to work. hmmmm  
[AS]var mouseListener:Object = new Object();  
mouseListener.onMouseWheel = function(delta) {  
trace(delta);  
trace(‘hello’);  
}  
Mouse.addListener(mouseListener);[/AS]
