Missing ViewModel definitions in Sencha Docs example for binding association

Hi ,

I am looking into the example of binding association as sited in sencha docs at below url http://ift.tt/1sSeseG.

The doc has details about the View part only and ViewModel definitions are missing. I am expecting that the missing ViewModel has the association definition, but is not yet added to the docs.

I am not able to prepare the missing ViewModel with association details. I am expecting that this example would have 2 model definitions. 1 for Customers and the other for Orders. I am not able to prepare these 2 parts and make the connection between them.

Can anyone help me in defining a sample ViewModel in this context.

Thanks
