Is there an accessible callback when Craft.EntryTypeSwitcher is run? When a user switches Entry Types in the control panel, Craft.EntryTypeSwitcher is trigged which in turn triggers onTypeChange.

Is there callback that a plugin can access to run some additional JavaScript after this event has occurred?

===== Edit to show Current work-around as per Justin's answer below ======

(function($) {
    Craft.LoadOverride = Garnish.Base.extend({
        init: function()
        {
            this.addListener(Garnish.$win, 'resize', 'runOverride');
        },
        runOverride: function()
        {
            console.log('Triggered!');
        }
    });
})(jQuery);
It looks like the only easy way to hook into that event is to listen for the resize event on the window object. On line 55, it is triggering resize(). Looking at the code, I am not seeing any other way to listen for these events. The Craft.EntryTypeSwitcher class is getting instantiated but not getting assigned to any variable in the DOM, so there is no way for you to grab that instance (from what I can tell anyway).
