do we reset the clock

[JS 20]

Beginning of the game last night. Two person crew and I'm the U. Jump ball goes up and is tipped opposite me, right down the division line. I chop when the jumper's touch it. It hits someone but i can't see who and neither can my partner so we rejump. I had the timer reset the clock to 6:00 (jv game). Second jump ball, jumpers touch simultaneously and send the ball down the division line and out OB opposite me. So we jump again and again I reset the clock. Was it right to reset the clock in both situations?
