Changing threshold in python does not update in any views

I want to use a shortcut to change the lower threshold of a foreground US volume to 1 (so that the black surrounding pixels disappear). I used the code from here, and this code changes the threshold in the GUI, however, it doesn’t ‘propagate’ to any of the views - nothing changes there. I still need to manually nudge the slider/value a bit for the view to be updated. Is there any command that needs to be executed for the view to be updated?
