title: ng-show in controller with $index
body: <p>I have list of items with <code>ng-repeat</code> and i need to show "Status" text next to an item on some event (like on click etc.), i found that i can use <code>$index</code> for, but can't understand how to use it in controller.
  HTML:</p>
  
  <pre><code>&lt;div ng-repat = 'item in items'&gt; {{item}} &lt;span ng-show = 'ShowItemStatus[$index]'&gt; Status &lt;/span&gt; &lt;/div&gt;
  </code></pre>
  
  <p>I using ng-show within controller and it looks like:</p>
  
  <p><code>$scope.ItemStatus = false</code>
  How i can get index within controller so it will looks something like <code>$scope.ItemStatus[$index] = false</code> - this not works for me.</p>
