title: Get AngularJS object property name in the markup
body: <p>Let's say I have an object:</p>
  
  <pre><code>$scope.Golovkin = {
      id:12,
      Like:0,
      Dislike:0,
      url:"https://twitter.com/GGGBoxing"
  };
  </code></pre>
  
  <p>And in the view I have a button:</p>
  
  <pre><code>&lt;input type="button" value="Like" ng-click="incrementLikes(Golovkin)" /&gt;
  </code></pre>
  
  <p>How do I replace the <code>value</code> of the button with the property name of <code>$scope.Golovkin.Like</code> as a string?</p>
