title: Backbone good model structure
body: <p>I would like to know your opinion about this structure. you have 3 or 4 part in the same page. And you used a main Model to control and communication between the another Model. I'm thinking that this is a good practice to reuse de code. What do you think about it?</p>
  
  <pre><code>     mainModel(comunication betwen submodel)
      /    |    \
   model  model  model
  </code></pre>
  
  <p>Thank you</p>
