How would I inject an API service into the ModalInstanceCtrl function - angularjs

Question

The following code is right from angular-ui getting started page: http://angular-ui.github.io/bootstrap/#/getting_started. I've modified it for a log in modal and would like to call the API that authorizes the user before the dialog is closed.
var ModalDemoCtrl = function ($scope, $modal, $log) {
$scope.items = ['item1', 'item2', 'item3'];
$scope.open = function (size) {
var modalInstance = $modal.open({
templateUrl: 'myModalContent.html',
controller: ModalInstanceCtrl,
size: size,
resolve: {
items: function () {
return $scope.items;
}
}
});
modalInstance.result.then(function (selectedItem) {
$scope.selected = selectedItem;
}, function () {
$log.info('Modal dismissed at: ' + new Date());
});
};
};
// Please note that $modalInstance represents a modal window (instance) dependency.
// It is not the same as the $modal service used above.
Here is where I'd like to be able to call the service. But I haven't been able to get the function to access anything I have that's external to it. It seems to recognize objects (hence items), but if I inject a service into ModalDemoCtrl I'm getting an undefined error when I try to access it.
var ModalInstanceCtrl = function ($scope, $modalInstance, items) {
$scope.items = items;
$scope.selected = {
item: $scope.items[0]
};
$scope.ok = function () {
$modalInstance.close($scope.selected.item);
};
$scope.cancel = function () {
$modalInstance.dismiss('cancel');
};
};

I believe this was answered previously somewhere on Stack, but even better here is a Plunkr for a concrete example:
http://plnkr.co/edit/4GcKLz?p=preview
angular.module('app', ['ui.bootstrap']).
service('DataService', ['$rootScope',
function($rootScope) {
this.data = {};
this.data.message = 'This is a message from a service';
this.data.items = ['item1', 'item2', 'item3'];
}
]).
controller('myModal', ['$scope', '$modalInstance', 'DataService',
function($scope, $modalInstance, dataService) {
$scope.data = dataService.data;
$scope.message = dataService.data.message;
$scope.items = dataService.data.items;
$scope.selected = {
item: $scope.items[0]
};
$scope.ok = function() {
$modalInstance.close($scope.selected.item);
};
$scope.cancel = function() {
$modalInstance.dismiss('cancel');
};
}
]).
controller('appController', ['$scope', '$modal', '$log', 'DataService',
function($scope, $modal, $log, dataService) {
$scope.data = dataService.data;
$scope.showModal = function() {
var modalInstance = $modal.open({
templateUrl: 'myModalContent.html',
controller: 'myModal'
});
modalInstance.result.then(function(selectedItem) {
$scope.selected = selectedItem;
}, function() {
$log.info('Modal dismissed at: ' + new Date());
});
};
}
]);
HTH!
