I couldn't make out exactly what you are trying to accomplish but this is what I got out of it...

1. You have a button, in this case button one or on a joystick usually the trigger, which is supposed to shoot a cannon.
2. You've stated that you have connected the button up to a true/false indicator and when you run code it doesn't work?

I would assume that your joystick is bad... Although that is pretty rare...
