How to show main ContextMenu when loadMovie()

in Mainframe of test1.fla

var newMovie_mc:MovieClip;
newMovie_mc=_root.createEmptyMovieClip(“New1”,2);
stop();
my_cm = new ContextMenu();
my_cm.hideBuiltInItems();
my_cm.customItems.push(new ContextMenuItem(“Load Movie.”, loadHandler,true));
my_cm.customItems.push(new ContextMenuItem(“Remove Movie.”, removeHandler,true));
function loadHandler() {
moVieLoad();
fscommand(“messagebox”, “This is a message box called from within Flash.”);
}
function removeHandler()
{
trace(“hoho”);
newMovie_mc.unloadMovie();
}
_root.menu = my_cm;
btnLoad.onRelease=moVieLoad;
function moVieLoad()
{
newMovie_mc.loadMovie(“test2.swf”);
}

and in mainframe of test2.fla

Stage.showMenu=false;

test1.fla and test2.fla have same Stage.width and Stage.height

How can use ContextMenu from test1.swf??
