Calling function from within onMotionChanged not working!

Hi there! Hopefully someone can help me with this . . . it seems simple enough.

I have a movieclip that tweens when you roll over or out it, which in turn is supposed to call a function from another class which adjusts clips according to the first clip’s position.

For some reason I can’t get any function to call from inside the onMotionChanged function? It will trace fine, but will not execute any function (regardless of where it is declared). What am I doing wrong?

Here’s the roll out function:

private function menuRollOut() {
		var thisObj = this;
		var thisObj = thisObj._parent;
		if (!thisObj.hitTest(_xmouse, _ymouse)) {
			var menu_tween:Object = new Tween(thisObj, "_x", Regular.easeOut, thisObj._x, 0-thisObj._width+15, 0.5, true);
			menu_tween.onMotionChanged = function() {
				trace("tweening");
				tweenFunc();
			};
		}
	}
