Virtual Joystick + Touch event problem (mobile)

Hi, I have some problems when trying to use touch event and virtual joystick at the same time.
In my game, the player can zoom in and out by pinching (with 2 fingers obviously), pan the camera by swiping and of course, moving with the virtual joystick.
My problem is that using virtual joystick is considered as a touch event, so if the player try to pan the camera while using the joystick, the game act as if it was a double touch event and zoom in/out
So, is it possible to exclude the virtual joystick from those touch events?

I still need help with this.

Hi Haoris, you used the default joystick or made his?
