run different functions each time the same button is pressed?

ahh, you're correct. Your code was working all along.

I just realised one button press is divided to the push and releasing of the button:

push:
BTN_TR
SYN_REPORT

release:
BTN_TR
SYN_REPORT

So if I push it down, it switches to the next mode. Upon releasing it switches again.

That was my mistake. Your code works great!
