Angular UI Bootstrap Modal Dialog Close Event

This works for clicking on the backdrop and pressing the esc key if you are opting in on that.

var modalInstance = $modal.open({
    templateUrl: '/app/yourtemplate.html',
    controller: ModalInstanceCtrl,
    windowClass: 'modal',
    keyboard: true,
    resolve: {
        yourResulst: function () {
            return 'foo';
        }
    }
});

var ModalInstanceCtrl = function ($scope, $modalInstance, yourResulst) {

    var constructor = function () {
       // init stuff
    }

    constructor();

    $modalInstance.result.then(function () {
        // not called... at least for me
    }, function () {
        // hit's here... clean up or do whatever
    });

    // VVVV other $scope functions and so on...

};

UPDATE: alternative approach

I have no idea why this way is not documented at http://angular-ui.github.io/bootstrap/ ... but I find it much better. You can now use that page's controller or use a specific controller with the controller as syntax. You could even utilize ng-include for the content of the modal, if you want separation on html. The following works with no JS needed in the controller to setup/configure the modal, as long as you have bootstrap/bootstrapUI included in your project/site

<div class="row">

    <button class="btn btn-default" data-toggle="modal" data-target="#exampleModal">Open Example Modal</button>

</div>

<div class="modal fade" id="exampleModal" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
    <div class="modal-dialog modal-lg">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal">Close</button>
                <h2 class="modal-title" id="exampleModalLabel">Modal Example</h2>
            </div>
            <div class="modal-body" style="padding-bottom:0px;">

                <h3>model markup goes here</h3>

            </div>
        </div>
    </div>
</div>

I finished with the following code:

$modal.open(modalOptions).result.finally(function(){
  console.log('modal has closed');
});

This way you can avoid the method then()

This worked for me:

var modalInstance = $modal.open({...});
        modalInstance.result.then(function () {
            //something to do on close
        });
