Question

## Performance question
A lot of databinding is in place, coupled with the model of the controller.

I wanna make more then one change and then let the visual changes to the
databinding happen, not step by step.

Question 1: Will UI-databinding trigger step-by-step when making
            changes within setupController?
            
Question 2: If so, is there a way to suspend such step-by-step
            changes, and make them add up until you resume? (Version 3)

setupController difference.js

    // Version 1
    setupController:  function( controller, model ) {
        var manager = controller.get('manager');
        controller.set('model', model); // Will databinding for UI evaluate here before manager.reset()?
        
        if (manager)
            manager.reset();
        else
            controller.set('manager', App.WorkManager.create());
    },
    
    // Version 2
    setupController:  function( controller, model ) {
        var manager = controller.get('manager');
        if (manager)
            manager.reset();
        controller.set('model', model); // If databinding evaluates directly I'd prefere this
        if (!manager)
            controller.set('manager', App.WorkManager.create());
    },
    
    // Version 3
    setupController:  function( controller, model ) {
        var manager = controller.get('manager');
        // Best solution would be - Part 1
        // ????.suspendRendering();
        controller.set('model', model); 
        
        if (manager)
            manager.reset();
        else
            controller.set('manager', App.WorkManager.create());
        
        // Best solution would be - Part 2
        // ????.resumeRendering();
    },
