How to deal with litle components with mvc+s?

Hello,
I'm a bit new in using robotlegs. I had to learn it for the sake of app, that I'm writing in my job. I've read Joel's 3-step tutorials about mvc+s in robotlegs and Im in the half of book about this framework.

My problem is about simple, little components, like buttons. In my case, I use buttons in my mxml form. In first Joels tutorial (about HelloWrold app), there was mediator and view just for one, single button. Does it mean, I have to make mediators and view for every single component in may app (list, button, etc)? It would result in hundreds of mediator and view classes when, if I made advanced application, so I doubt it's the right assumption.

Here are I my Main.mxml view file and MainMediator.as class in which I whanted to avoid defining 2 new views and mediators for back and next buttons and made it a bit different way. Could you please tell,if it is the right with mvc way or what made I wrong? I would appreciate it.

Main.mxml:

    <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
