Help needed about contextmenu and hitarea

I want to define hitarea of contextmenu items. My code is:

code:

---

var menu_cm:ContextMenu = new ContextMenu();

menu_cm.hideBuiltInItems();

var del_cmi:ContextMenuItem = new ContextMenuItem("sil (delete)");

del_cmi.separatorBefore = true;

menu_cm.customItems.push(del_cmi);



function firstDrag():void {

	if (isMenuOpen==true) {

		// ...

		newSymbol.hitArea = newSymbol.invisible_btn;

		removeChild(menuBack);

		

		newSymbol.contextMenu = menu_cm;

		del_cmi.addEventListener(ContextMenuEvent.MENU_ITE  M_SELECT, delSelected);

				

		// ...

	}

}
