backbone.js facebook api direction required

[abdul-mannan]

hi guyz
i've an app in facebook developed in codeignitor at the backend and on the front end simple ajax calls are used to update the page. All my page html is created dynamically in code ignitor and now the app has grown so much that i needed to shift my code to some client side framework. for this, i found out backbone.js as good client side framework.but i've few problems in choosing how to shift/ translate my code or what changes do i need to make at my current client side and php code to use backbone.js.

Also i've a confusion that currently my page's html is built dynamically from codeignitor and passed on through ajax call and then displayed. As for backbone, how can i work with this dynamically created html?
As far as i have learnt, backbone.js can work with templates ( underscore or any other ) but how can i my dynamic html to some template?
I also studied require.js which is a javascript module loader to load the template or js files. If i can get any direction on how can i move from my current design to something client side framework and how?
For me, this is necessary and i can't leave out this option. I have to now use backbonejs to make things simple and RESTful.
Plz help guyz
Thnx
