I am trying really hard to understand the underlying lifecycle of a component creation and sometimes I really get confused. Like now
I don't understand what doesn't make addChild to actually add a child and display it on non Container component.
e.g . MyNumericStepper.addChild(new Button()) won't display any button somewhere in the stepper(off course !) but i can't see why in the code; because it's going anyway all the way to UIComponent.$addChild(child:DisplayObject):DisplayObject
