title: How to execute a function defined in a controller attached to a previous page after ons.navigator.popPage() ?
body: <p>I discover Onsen UI and I have a problem : </p>
  
  <p>1- I defined 2 pages <code>page-1.html</code> and <code>page-2.html</code> with a controller attached (<code>page1Ctrl</code> and <code>page2Ctrl</code>). </p>
  
  <p>2- I defined a function in page1Ctrl to go to the page-2.html :</p>
  
  <pre><code>$scope.ons.navigator.pushPage('page-2.html');
  </code></pre>
  
  <p>which executes <code>page2Ctrl</code></p>
  
  <p>3- In this page, i have a button which executes a code that returns on <code>page-1.html</code> (with <code>popPage()</code>). This function is attached to <code>page2Ctrl</code> :</p>
  
  <pre><code>function page2Ctrl($scope) {
      $scope.functionToPopPage = function() {
  
          // &gt;&gt;&gt; Here I would like to execute a function attached to page1Ctrl
  
          $scope.ons.navigator.popPage();
      };
  }
  </code></pre>
  
  <p>4- then, i want to launch a function defined in the <code>page1Ctrl</code>, <strong>how could i process it ?</strong></p>
  
  <p>Thanks</p>
