title: How to use Backbone collection's create method correctly
body: <p>I found that when I use the collection.create to create a new model, backbone will send a post request, but the post data is incorrect
  for example
  collection.create({name:'test'})
  backbone will send POST data using "{name:'test'}" as key, and "" as value,
  but I want the POST data by using name as key, 'test' as value,
  can anybody no how to setting it,</p>
  
  <p>I use django as the server</p>
  
  <p>thanks in advance</p>
