Sure, this is one of those 'You have to see it to call it'. But if he is celebrating his lay-up by slapping the backboard, then he gets slapped with a Technical.

To answer your question: It's not clear in the OP. It's also not clear in the OP if there was a defensive player attempting to block the shot which may have caused the offensive player to go up strong with two hand and with the follow through slapped the backboard. Is there?
