Technical Foul for going OOB

[Exkalybr]

I need a little clarification here guys, the dribbler, when forced out of the field of play loses the dribble through incidental contact, and then re-establishes themselves in-bounds and regains the ball, should be allowed to continue play without penalty, is this correct? I had a coach jump on me that a technical should have been called when one of his players, forced the dibbler to the baseline, tipped the ball away from the dribbler who went out of bounds momentarily, came back in and established position on the court, and picked up the dribble again to continue up court. I did not T-up the player thinking they had been forced from the field of play, allowing for the fact that the player did not foul the defender getting back to the ball, but the coach did not let up until the the next dead ball, where I explained my ruling to him and his assistant. Let me now what you all think. Thank you
