Can't fire a Custom Event on UI Button Touch OnClick

Hey Everybody.

I created a Custom event on my HUDManager to fire when the user clicks on the button:

public delegate void HUDManagerEventHandler();
public static event HUDManagerEventHandler OnClickDrawPath;

So, when user click in the button, i call this method (with the event fire):

public void StartDraw ()

So, when i click with mouse on editor, the event OnClickDrawPath is fired, but when i touch the button, via Unity Remote or Android Build, nothing happpens.

How can i make the touch also fire the event?

You need to include an event system and a canvas that contains a mobile control rig in every scene.
