To reverse or not

[Carson256]

I coach at a small high school and had this situation come up the other night.

One of our players drove the basket threw up a shot which barely grazed the backboard. He then caught the rebound and was about to score the layup, when the official under the hoop said the ball hadn't touched the backboard and ruled it traveling. The other official then said it did touch the backboard, but he said they couldn't reverse it since it was a traveling call. Is this call reversable, and if so is it a jump ball or is it possesion of the team that came down with rebound?
