So firstly you would have to be aware of the state change that effects
the visual.... i.e your model object would be listening to something.

When the state change happens your model object would respond in some
way, for example, setting it's active image to some new image reflecting
the state change, then it would in turn fire an event that its edit part
would be listening for.

The edit part would respond to this event by calling refreshVisuals() on
itself. Part of refreshVisuals() would be to ask the model object for
the image to display.
