title: Angularjs sorting in descending order
body: <pre><code>{
  "35": "testing",
  "46": "tst123",
  "51": "alpha_circular",
  "56": "test4",
  "60": "alpha_price",
  "64": "test_attached",
  "70": "test789",
  "71": "new cir",
  "73": "valid"
   }
  </code></pre>
  
  <p>I need to sort the above data in descending order based on the key. How can I achieve it?</p>
  
  <p>Also I have used <code>ng-repeat="(id,value)"</code> in lists track by <strong>$index</strong>". Can I apply filters in this case?</p>
