Here's my take on this; instead rendering the whole view on every change, in interactive views, use the view's jQuery or plain JS contexts just like your non-MVC example.

As the Backbone docs say:

"Two way data-binding" is avoided. While it certainly makes for a nifty demo, and works for the most basic CRUD, it doesn't tend to be terribly useful in your real-world app. Sometimes you want to update on every keypress, sometimes on blur, sometimes when the panel is closed, and sometimes when the "save" button is clicked.
