Assume you are using a bound array named links that is defined like [{link: 'some link', title: 'my nifty link', active: true}, ...]

//in JS file. I will assume you have an app called MyApp that was create with Em.Application.create()

MyApp.linksController = Em.ArrayProxy.create({
  content: [ { link: 'I am a link', title: 'I am a title', active: true } ] 
});
