1) Not be amiss to add csrf token in your backbone forms and turn it on in application controller:
#TODO add here code to empty the session
<input name="authenticity_token" type="hidden" value="<%= $('meta[name="csrf-token"]').attr('content') %>">
That works fine but I doubt that it is really necessary because browsers have ajax crossdomain restrictions anyway.
I am right or not?
2) I just found it handful when you have multiple fields in your forms use backbone-syphon-rails gem. It doing form serialisation for you and you can write something like that:
createNote: (event) ->
data = Backbone.Syphon.serialize(this)
