Ump position?

[Shef24]

The other night I was working a High School game, partner in C position and I behind the plate, runners on 1st and 2nd, there is a hit to the left field gap that the left fielder makes a diving attempt to catch the ball. I see the ball hit the kids glove, I don't see it come out, but the kid gets up off the ground and shows the ball, but it is now in his bare hand. When the kid hit the ground the ball popped up from the glove and he caught it bare handed, this is what he said after the game.

My question is, who should have had the out call? My partner at C or me from down the third base line?
