Angular2更新绑定

Question

我有一个小问题。我会告诉这个例子我的问题：

export class UserComponent { 
     users: User[] = new Array<User>(); 
     removeAll(){ 
     this.users = new Array<User>(); 
     } 
    } 

<button (click)="removeAll">Remove</button> 
<ul> 
<li *ngFor="let user of users>{{user.name}}</li> 
</ul> 

当我删除按钮，点击它们应该是空的，但UL拥有所有先前的值。如何刷新绑定？ 感谢

Answer 1

(click)="removeAll" 

应该

(click)="removeAll()"
