Returning data from angular $uibModal backdrop click
<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>
