title: $scope.currentPage not updating - Angular Ui Pagination
body: <p>I have this <a href="http://codepen.io/anon/pen/WQXwYY" rel="nofollow">codepen</a>, and using the function <strong><code>'$scope.pageChanged'</code></strong> to see when a page is changed.</p>
  
  <pre><code>$scope.pageChanged = function() {
   $log.log('Page changed to: ' + $scope.currentPage);
  };
  </code></pre>
  
  <p>But when I click on page links (changing a page), the variable <strong><code>'$scope.currentPage'</code></strong> doesn't changes. Why?</p>
  
  <p>I think is something about the <strong><code>filter</code></strong>, but not sure.</p>
