How to prevent touch to propagate through new UI Button?

Hi All,

I have couple of buttons on the screen and unfortunately when I press one of these buttons the touch propagates through to the screen below which then gets handled by a separate Update() function used to handle touches off the UI buttons.

I've tried to utilize the new Eventsystem, but so far with now success. Here's my code:

 private bool WasAButton()
 {
     UnityEngine.EventSystems.EventSystem ct
         = UnityEngine.EventSystems.EventSystem.current;
     
     if (! ct.IsPointerOverGameObject() ) return false;
     if (! ct.currentSelectedGameObject ) return false;
     if (ct.currentSelectedGameObject.GetComponent<Button>() == null )
         return false;
     
     return true;
 }
 
 
 void Update () 
 {
     if (Input.touchCount > 0)
     {
         if (!WasAButton())
         {
             Input.ResetInputAxes();
             DoSomething();
         }
     };    
 }

DoSomething() gets called even if the touch is on top of a UI button. Buttons work well, but I'd like to make sure that DoSomething() does not get called when pressing a UI button.
