我正在使用Ember 3.16.3，我得到这个错误的以下代码：
错误：Assert失败：必须将函数作为第二个参数传递给on修饰符

//login.hbs

 <form {{on "submit" this.login}}>
       <Input type="email" placeholder="email" @value={{this.email}} />
      <button type="submit">login</button>
 </form>

。

//login.js

import Route from '@ember/routing/route';

import { tracked } from '@glimmer/tracking';
import { action } from '@ember/object';

export default class LoginRoute extends Route {

   @tracked email = '';

   @action
   login(event) {
     event.preventDefault();

     // do some operations ...
  }
}
