How do make a joystick overlay for mobile scroll with viewport?

Got as far as duplicating this implementation perfectly within my game but can not figure out how to make the joystick scroll as the viewport scrolls:

I am using the fana version included in this Construct file.

I tried making the joystick objects on a layer that has 0 parallax but I can not figure out how to get it to work. The following version of the game has the joystick objects on the character layer with 100% parallax.

Here is a link to my current game:

Would greatly appreciate any help on this! Please let me know if I didn't explain well enough.

Wow I am continually amazed by this community, thanks so much. Worked perfectly. I had no idea you could specify layers with touch.
