title: File pick with Angular JS
body: <p>I would like to pick up a file with AngularJS:</p>
  
  <p>HTML:</p>
  
  <pre><code>&lt;div ng-controller="TopMenuCtrl"&gt;
      &lt;button class="btn" ng-click="isCollapsed = !isCollapsed"&gt;Toggle collapse&lt;/button&gt;
      &lt;input type="file" ng-model="filepick" ng-change="pickimg()" multiple /&gt;
      &lt;output id="list"&gt;&lt;/output&gt; 
  &lt;/div&gt;
  </code></pre>
  
  <p>javascript:</p>
  
  <pre><code>angular.module('plunker', ['ui.bootstrap']);
  function TopMenuCtrl($scope) {
      $scope.pickimg = function() {
          alert('a');
      };
  }
  </code></pre>
  
  <p>How can I bind the input file <code>onchange</code> action on the AngularJS <code>pickimg</code> function?
  And how can i manipulate the files uploaded after?</p>
