Converting into an Object-Orientated programme

Your code looks good aswell, although I think there are more efficient ways to program object orientated than how you're doing it now. I've edited your controller-object into something that is more effective (imo). The namespace (APP) also prevents any bugs or name collisions in your code.

On a side note, I would use a 'data-route' attribute in your html to track all the different buttons. After you've given your elements a data-route attribute, you can easily use a for-loop in your clickEvents function to look which button is clicked, instead of writing a click(function()); button for every element.
