Python • tkinter not using command in button

#I am trying to create an app that identifies a license plate and currently I have the camera running a screen developed that periodically looks #at the camera image and checks to see if there is a license plate (not finished) but the problem I have currently is the setup button doesn't fire t#he command. I have included the code for review and comment. Any suggestions would be appreciated.
