dictionary not updating itself

currently I am working on generating a window with a check box on it. I want the window to run a function to generate a dictionary by default, change the values of this dictionary when the check button is clicked and get back to the values generated from the default function if is unchecked. The problem is that when I un-check the checkbox the values of the dictionary do not change. I am very new to object-oriented programing and I really do not understand why this is happening

The data I am working on are segmented cell nuclei images that I got from StarDist 2D
