DPad module Problem

Hello,

i have a problem with following joystick module http://developer.coronalabs.com/code/simple-analog-stick-joystick-module.

I want to use 2 of them in my Game. 

But when i touch the display while i drag the joystick it cancels the drag.

multitouch is activated.

How can i make it work that the joystick dont lose the drag when i touch the screen?

Thanks for help
