Function did not get called in FuncAnimation?

I am doing a project for a bot cleaning room. I use the generator function to generate the random spots for finished cleaning and I want to show the progress in an animation. I doubt if the updateGrid function gets called. I looked at the documentation and did not fully understand the details. should I return something from the updateGrid function? What is wrong with my code? Thanks million!
