How to convert angular 1 modal service into typescript angular 2?

Question

I really would like to convert the following code to angular 2. Would it consist of writing alot of extra logic? Notice how this is simple and straight to the point.

I have a modal service

angular.module('app').service('myModalService', function ($modal, $http, $filter, $document) {
this.QuestionModal = function (message, title, showButtonNoCancel, buttonYesOK, buttonNoCancel) {
        return $modal.open({
            backdrop: 'static',
            keyboard: false,
            templateUrl: 'Scripts/Services/questionModal.html',
            controller: function ($scope, $modalInstance) {
                $scope.vm = { Message: '', Title: title };
                $scope.vm.Message = message;
                $scope.YesOkButton = buttonYesOK;                
                $scope.ButtonNoCancel = buttonNoCancel;                
                $scope.ShowButtonNoCancel = function () {
                    return showButtonNoCancel;
                }
                $scope.Ok = function () {
                    $modalInstance.close(true);
                }
                $scope.Cancel = function () {
                    $modalInstance.dismiss('cancel');
                }
            }
        });
    };

I call it like this and get the return value

 myModalService.QuestionModal("Do you want to delete the order?", 'Cancel Order', true, "Yes", "No").result.then(
            function () {
                 //handle yes function here
            },
            function () {
                //handle no function here
                return;
            });
