Team control foul?

[Ref_in_Rehab]

Here's the scenario...
Summer tournament, HS varsity boys game.

2 on 1 fast break, A1 sees A2 trailing behind and lays the ball off the glass for A2 to dunk. B1 however jumps to retrieve the ball after it hit the glass and is fouled by A2 who goes through B1 in his attempt to dunk.

I called the foul on A2, and not thinking things through, we shot bonus FT's as that foul was the seventh on team A for the half.

A buddy asked me for an explanation, and after thinking it over, we agreed it was a team control foul, thus no FT's should have been awarded. I knew it was a pass attempt so team control was still in effect, right?

Anyone confirm or deny? NFHS and NCAA opinions welcomed.
