Angular 2中的进度条

Question

Angular 2中的进度条，我已经尝试过此代码，但是有人提出错误请帮助解决此问题

var myApp = angular.module('myApp',[]);
//myApp.directive('myDirective', function() {});
//myApp.factory('myService', function() {});
function MyCtrl($scope) {
    $scope.step = 1; 
    $scope.next = function(){
              
    $scope.step++;
   
       
   
      };   
    }

function MyCtrl1($scope) {
    $scope.step1 = 10;
        };
        

<div ng-controller="MyCtrl">{{step}} <br>

    <progress value="{{step*1}}" max="10"></progress> 
   <div ng-controller="MyCtrl1">{{step1}} <br>
    <a ng-click="next()">next</a> 
    
</div>
