title: Returning data from angular $uibModal backdrop click
body: <p>I'm trying to pass back a value from a uibModal. I can define the return if the user clicks the modal's close button</p>
  
  <pre><code>$scope.close = function () {
      $modalInstance.close($scope.editMade);
  };
  </code></pre>
  
  <p>But this doesn't work if the user click the backdrop area. </p>
  
  <p>How can I define a return value for that particular event?</p>
