Ember.js 在Ember 2.2中创建表单选择列表

嗨，我正在尝试创建一个选择列表作为登录表单的一部分。表单提交并传递两个输入文本值，但看不到选择列表

<form id="form-login" {{action 'authenticate' on='submit'}}>
    <fieldset>
        {{input id='identification' value=identification placeholder='Username'}}
        {{input id='password' value=password placeholder='Password' type='password'}}

        <select id="language" name="language">
            <option value="ENG">English</option>
            <option value="">Not English</option>
        </select>
    </fieldset>

    {{#if errorMessage}}
    <div>
        <strong>Login failed:</strong> {{errorMessage}}
    </div>
    {{/if}}

    <button type="submit" class="btn btn-default">Login</button>
</form>

那是我能找到的唯一一页他们的文档

谢谢

需要在上下文中设置所选值。目前根本没有设置该值

控制器

import Ember from 'ember';
export default Ember.Controller.extend({
  language: 'English',
  languages: ['English', 'Non English'],
  actions: {
    authenticate() {
      // Set values from form and submit to server...
    }
  }
});

模板

<form id="form-login" {{action 'authenticate' on='submit'}}>
  <fieldset>
    {{input id='identification' value=identification placeholder='Username'}}
    {{input id='password' value=password placeholder='Password' type='password'}}

    <select onchange={{action (mut language) value="target.value"}} id="language" name="language">
      {{#each languages as |languageChoice|}}
        <option value={{languageChoice}} selected={{eq language languageChoice}}>{{languageChoice}}</option>
      {{/each}}
    </select>
  </fieldset>

  {{#if errorMessage}}
    <div>
      <strong>Login failed:</strong> {{errorMessage}}
    </div>
  {{/if}}

  <button type="submit" class="btn btn-default">Login</button>
</form>

{{input id='identification'value=标识占位符='Username'}
{{input id='password'value=密码占位符='password'type='password'}
{{{每种语言作为{语言选择}
{{languageChoice}}
{{/每个}}
{{{#如果错误消息}
登录失败：{{errorMessage}
{{/if}
登录
