TouchEvents don't work in AIR3.3 ????

I've been testing with MouseEvents so I can test on my computer.

Now that I'm almost done my app .. I've converted all MouseEvents to TouchEvents...  they arent working.. nothing happens when I touch the item.   Am I missing something here ?  This should be simple ?

Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;

mainHomeBTN.addEventListener(TouchEvent.TOUCH_BEGIN, fl_mainHomeBTNdown);

function fl_mainHomeBTNdown(event:TouchEvent):void

{

trace("Touch Began");

}

mainHomeBTN.addEventListener(TouchEvent.TOUCH_END, fl_mainHomeBTNup);

function fl_mainHomeBTNup(event:TouchEvent):void

{

          trace("Button was tapped");

}
