如何让Aurelia验证工作

我从http://aurelia.io/hub.html#/doc/article/aurelia/validation/latest/validation-basics/1

Then try http://blog.durandal.io/2016/06/14/new-validation-alpha-is-here/

然而，验证不会像预期的那样发生在blur上。即使我在控制器上调用validate，也不会设置错误。

login.ts

import {inject, NewInstance} from 'aurelia-dependency-injection';
import {ValidationController} from 'aurelia-validation';
import {ValidationRules} from 'aurelia-validatejs'
@inject(NewInstance.of(ValidationController))
export class Login {
    email:string;
    password:string;
    controller = null;
    constructor(controller){
        this.controller = controller;
    }
    submit = () => {
        this.controller.validate().then((res) => console.log(res)).catch((e) =>console.log(e));
    };
}
ValidationRules
    .ensure('email').required()
    .on(Login);

login.html

<form submit.delegate="submit()">
                <div class="form-group">
                    <label for="email" class="control-label required">Email</label>
                    <input class="form-control" value.bind="email & validate" type="email" id="email">
                </div>
                <div class="form-group">
                    <label for="password" class="control-label required">Password</label>
                    <input class="form-control" value.bind="password & validate" type="password"
                           id="password">
                </div>
                <div class="form-group">
                    <input id="remember_me" name="remember_me" type="checkbox" value="1">
                    <label for="remember_me" class="control-label">Remember me</label>
                </div>
                <div class="form-group">
                    <button class="btn btn-primary btn-block" type="submit">Login</button>
                </div>
            </form>
