Touch Event Help

programming flash

The code below is using quickbox2d and i am trying to add a touch feature so I can use this on my air android apps. I am trying to just make certain items draggable not all. But my touch methods dont seem to fire off. Also how do I get scope of a crcle that is drawn using the quickbox2d class?

package
{

    import flash.display.StageAlign;
    import flash.display.StageScaleMode;
    import flash.display.MovieClip;
    
    import flash.events.TouchEvent;
    //import flash.events.TransformGestureEvent;
    import flash.ui.Multitouch;
    import flash.ui.MultitouchInputMode;
    
    
    import com.actionsnippet.qbox.*; 
    
    public class Box2d extends MovieClip
    {
        public var testMC:MovieClip = new test_mc() as MovieClip;
        
        public function Box2d()
        {
            Multitouch.inputMode=MultitouchInputMode.TOUCH_POINT;
            trace("Box2d");
            
            // support autoOrients
            stage.align = StageAlign.TOP_LEFT;
            stage.scaleMode = StageScaleMode.NO_SCALE;

        
            var sim:QuickBox2D = new QuickBox2D(this);
