What is the correct procedure?

[dave30]

Team A inbounds the ball at the baseline (backcourt). Player dribbles to midcourt. I notice that the clock never started. (actually my partner noticed, the clock was behind me) I take the ball back to the baseline and Team A throws the ball in again. Only this time, Team B decides to press. Team B steals the ball and scores. The coach argues that I should have taken some time off the clock and gave them the ball at midcourt since it wasn't their fault that the clock didn't start. He had a point. I told him I honestly didn't know the correct procedure, but did what I thought was correct. Was I wrong?
