What's your call?

[Rufus]

Well, 9.2.10 states:

The opponent(s) of the thrower shall not have any part of his/her person through the inbounds side of the throw-in boundary-line plane until the ball has been released on a throw-in pass.

Then, under penalities:

3. If an opponent(s) of the thrower reaches through the throw-in boundary-line plane and touches or dislodges the ball while in possession of the thrower or being passed to a teammate outside the boundary line (as in 7.5.7), a technical foul shall be charged to the offender. No warning for delay required.

7.5.7 is a pass out of bounds from one player to another after a made basket which doesn't apply in your scenario in that your player is trying to inbound the ball.

Based on all of the above I believe you got no call since the ball's already been released before the contact is made.
