NBA 2K14 Stepback Jumpshot

Can anybody tell me exactly how to do (or show me a video with) a stepback jumshot.
Cause it is the only thing i can´t do in Training Camp!

edit: I did it you can delete this thread!

If your in PC . while moving/driving . Just Tap shoot button and your movement keys away from the basket at the same time

In xbox ps3 or gamepads . while moving/driving . just tap shoot button and left stick away from the basket at the same time
