Starting a large survey application

If that's the majority of your app, you may want to look at using Angular.js

I've only started playing with it, but its data binding seems very simple straight out of the box, whereas I think backbone.js is a bit more bare bones and would require you to set up a lot more on your own.

I think you could work through this tut and set up your app in about a day.
