Dragging a movieclip as3 - actionscript-3

Question

I have a Movieclip which is a child of another movieclip. I use startDrag() and stopDrag() with first (parent) Movieclip but the nested one doesnt move. Why?
relevant code on stage:
var main:rt = new rt(); // rt being a class in my library, which extends MovieClip object.
addChild(main);
stage.addEventListener(MouseEvent.MOUSE_DOWN, stage_mousedownHandler);
stage.addEventListener(MouseEvent.MOUSE_UP, stage_mouseupHandler);
function stage_mousedownHandler(event_object:Event) {
main.startDrag();
}
function stage_mouseupHandler(event_object:Event) {
main.stopDrag();
}
rt's constructor code:
public function rt() {
var bmp_bar:Bitmap;
var br_male:Bar_male; // Bar_male is a Bitmap in my library. (AS Linkage)
bmp_bar = new Bitmap(br_male);
this.addChild(bmp_bar);
}

Made this simple program to test and it works as expected in Flash Develop, there is a main sprite and a child bitmap when I mouse down any where on stage the main sprite is dragged and the child bitmap is moved.
So I am guessing there is something going on in your workflow in flash professional and linkage. Make sure the mouse event handlers are triggered put some breakpoints and debug.
package
{
import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.display.Sprite;
import flash.events.Event;
import flash.events.MouseEvent;
import flash.geom.Rectangle;
public class Test extends Sprite
{
private var sp:Sprite = new Sprite();
public function Test()
{
addEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
}
private function onAddedToStage(e:Event):void
{
removeEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
var bmpData:BitmapData = new BitmapData(100, 100,false,0x000000);
bmpData.fillRect(new Rectangle(0, 0, 100, 100), 0xff0000);
var bmp:Bitmap = new Bitmap(bmpData);
sp.addChild(bmp);
addChild(sp);
stage.addEventListener(MouseEvent.MOUSE_DOWN, onMouseDown);
stage.addEventListener(MouseEvent.MOUSE_UP, onMouseUp);
}
private function onMouseUp(e:MouseEvent):void
{
sp.stopDrag();
}
private function onMouseDown(e:MouseEvent):void
{
sp.startDrag();
}
}
}
