Passing modal data in AngularJS using controller as and vm - angularjs

Question

I have a pair of controllers that looks like this:
(function () {
'use strict';
angular
.module('room')
.controller('RoomGetCtrl', Room)
.controller('TestCtrl', Test)
Room.$inject = [...'$uibModal'...];
Test.$inject = [...'$uibModalInstance'...];
function Room(..., $scope, $uibModal) {
var vm = this;
...
vm.open = function (size) {
vm.modalInstance = $uibModal.open({
templateUrl: 'modal.html',
controller: 'TestCtrl as vm',
});
};
}
function Test(???){
this.modalText = 'Modal Text'
this.modalCancel = function() {
???.dismiss();
}
}
})();
The view looks like this:
<script type="text/ng-template" id="modal.html">
<div class="modal-header">
<h3 class="modal-title">Modal window</h3>
</div>
<div class="modal-body">
<pre>{{ vm.modalText }}</pre>
</div>
<div class="modal-footer">
<button class="btn btn-default" ng-click="vm.modalCancel()">Cancel</button>
</div>
</script>
<button type="button" class="btn btn-default" ng-click="vm.open()">Open me!</button>
...
The above works, except that I'm unable to figure out what goes in the ??? in Test() above. I've tried a variety of things, whenever I click the cancel button, the console logs an error along the lines of "x.dismiss is not a function," where "x" is whatever I've tried use.
Any help?

Nevermind. I instantaneously worked it out myself (I swear, posting the question makes me think better). Anyway, here:
(function () {
'use strict';
angular
.module('room')
.controller('RoomGetCtrl', Room)
.controller('TestCtrl', Test)
Room.$inject = [...,'$uibModal'];
Test.$inject = [$uibModalInstance];
function Room(..., $uibModal) {
/*jshint validthis: true */
var vm = this;
...
vm.open = function () {
vm.modalInstance = $uibModal.open({
templateUrl: 'modal.html',
controller: 'TestCtrl as vm',
});
};
}
function Test($uibModalInstance){
this.modalText = 'Modal Text'
this.modalCancel = function() {
$uibModalInstance.dismiss();
}
}
})();
Really simple. $uibModalInstance.dismiss();. It was right there in the documentation
