Callback multiple button objects

[Pegasus3]

Hi all,

I am designing an interface with multiple buttons as shown in screenshot named buttons. I want to run all as per the user need and I wrote following code (please see snapshot named code)
1001

1002
But the issue is only the function which I defines at the last works and others not work for callback. Can someone help me out in this issue.

Try registering the callback functions for button presses using vizact.onbuttondown:

vizact.onbuttondown(exitButton, onExitButton)
vizact.onbuttondown(pauseButton, onPauseButton)
vizact.onbuttondown(resumeButton, onResumeButton)

Yes I tried but got another error (PFA screenshot)
