Can't Find This Rule!

[Bishopcolle]

A-1 lets fly a three point attempt which I signal....while the ball is in the air, B-1 pushes A-2 underneath trying to position for the rebound....The 3-point attempt is good which I signal...The Lead Official called B-1 for the push, and we're in the bonus, so he signals two foul shots, and reports to the table....B Coach adamantly tells him we only shoot one foul if the 3-point attempt is good.....I know he is wrong, but in the heat of the moment, doubt sets in....He asked me as Ref for the correct rule, and I told him "No team control on the attempted shot....we shoot two for the foul in the bonus." Did we get it right?
