Casebook play - pushing foul on rebounded while shot is in the air

[WhistlesAndStripes]

Can anyone tell me if there's a casebook play addressing the following situation:

Player a one attempt to three-point shot. While the shot is in the air, B1 pushes 82 while jogging for rebounding position. As the try goes through the hoop, the official blows his whistle for the file on B1. Both teams are in the double bonus.

My partner who had made the call, got a little bit confused and couldn't explain to the coach. So I did. I told the coach that because we were in bonus, that the shot counted, and then the player who got pushed would be shooting two free throws for the double bonus. The coach believed that the other team should just be given the ball back from Outabounds throw in underneath the basket.

Can anyone site for me if there's a kids book play addressing this.?
