Since your link to this approach is down i decided to complement your excelent answer so anyone can use it:

In order to execute the following javascript command:

url: Routing.generate('state_list'),

You need to install FOSJsRoutingBundle that can be found in here.

ATENTION: in the read me section of the bundle there are instalation instructions but there is something missing. If you use the deps with this:

[FOSJsRoutingBundle]
git=git://github.com/FriendsOfSymfony/FOSJsRoutingBundle.git
target=/bundles/FOS/JsRoutingBundle

You must run the php bin/vendors update before the next steps.

I'm still trying to find out what route is needed in the routing.yml for this solution to work. As soon as i discover i will edit this answer.
