Simulate Mouse click Button on Key Input

[Danim3D]

I am trying to Simulate a Mouse click on an NGUI Button with a Keyboard Input.

I have try the UIKeyBinding script and this line bellow but the UIPlayAnimation and fonction doesn't execute, only the sound play.
I would like to know what I'm doing wrong. Thank!

if(Input.GetKeyUp(KeyCode.Escape))
      buttonGameObject.SendMessage("OnClick", SendMessageOptions.DontRequireReceiver);

Open up UIPlayAnimation.cs, find the OnClick function and change it to be:

1.         void OnClick ()
2.         {
3.                 if (UICamera.currentTouchID == -2 || UICamera.currentTouchID == -3) return; // <-- this changes
4.                 if (enabled && trigger == Trigger.OnClick) Play(true, false);
5.         }
