app running on simulator but not in ipad..! - iphone

Question

A'm stucked with a very strange problem.....really cant get how to come out with that..!!
I am developing iPad application in which I am drawing a 3d cube with openGL programming for ipad....Everything is fine....I drawn the cube and also colored it with different colors....This all things I have tested on simulator, everything is great. But when I tried to test on iPad, my cube is being drawn but coloring part is not working...!!!
Thanks in advance for help..!!

UPDATE : My sample code
MyViewController.h
CubeView *cubeView;
MyViewController.m
cubeView = [[CubeView alloc] initWithFrame:CGRectMake(250, 60, 450, 600)];
cubeView.multipleTouchEnabled = YES;
cubeView.backgroundColor = [UIColor clearColor];
[self.view addSubview:cubeView];
