Input.touch webgl doesnt work

Hi im trying to get Input.touch to work on a mobile device with a WebGL port for a simple game, i using the following code :

 #pragma strict
 public var projectile: GameObject;
 public var clone: GameObject;
 function Update() {
     for (var i= 0; i < Input.touchCount; ++i) {
         if (Input.GetTouch(i).phase == TouchPhase.Began)
             clone = Instantiate(projectile, transform.position, transform.rotation) as GameObject;
     }
 }

Any suggestions what im doing wrong, in the game preview in unity it works fine, but when loaded on a mobile device, the touch doesnt repsond.

Thanks
