Model binding not working in Angular UI Bootstrap modal

I have simple example using Angular UI Bootstrap modal service. In this example I don't understand why model binding is not working. Instead of seeing "Doing something..." on modal dialog I see "{{message}}". What I need to change?

Example is here: http://ift.tt/1GSzNbt

modal html looks like this:

<div ng-app="myModule">
    <div ng-controller="modalInstanceController" class="modal-body">
        <div>{{message}}</div>
    </div>
</div>

And definition of module and controllers:

var myAppModule = angular.module('myModule', ['ui.bootstrap']);

myAppModule.controller('modalInstanceController', function ($scope, $modalInstance, message) {
    var vm = this;
    vm.message = message;
});

myAppModule.controller('myController', function ($scope, $modal) {


        $scope.open = function open() {

            var modalInstance = $modal.open({
                templateUrl: 'modal.html',
                backdrop: 'static',
                //windowClass: 'custom-modal-wait',
                dialogFade: false,
                keyboard: false,
                controller: 'modalInstanceController',
                resolve: {
                    message: function () {
                        return "Doing something ...";
                    }
                }
            });

            setTimeout(function(){
                modalInstance.close('close');
                },5000);
        }

});
