角度2形式 – 在子组件级别分配ngControl

在角度2表格中,
尝试通过ngSubmit获取数据.
我可以在我的表单组件中分配ngModel和ngControl属性,但是在MyInput子组件中,我不能在没有“不提供错误”的情况下分配ngControl.
Plunker这里 http://plnkr.co/edit/LauhEz6vMaEmIg0hceoj?p=preview

directives: [CORE_DIRECTIVES,FORM_DIRECTIVES,MyInput],template: ` <div>
                <form #hf="ngForm" (ngSubmit)="onSubmit(hf.value)">
                    <div>
                      In Form: <input type='text' [ngControl]="inform" [(ngModel)]="theValue" [required]="req" #spy >
                      <br>Classes: {{spy.className}}
                      <br>
                      <br>In Component: <my-input [props]='prop'></my-input>
                      <br>In Component: <my-input [props]='prop2'></my-input>
                    </div>
                    <button type="submit" [hidden] = "!editing">Save</button>
                    <button type="button" (click)="cancelClick()" [hidden] = "!editing">Cancel</button>
                    <button type="button" (click)="setEdit(true)" [hidden] = "editing">Edit</button>
                </form>
                Form Values {{data}}
           </div>
            `

子组件模板：

@Component({
selector: 'my-input',directives: [FORM_DIRECTIVES],template: ` 
            <input type='text'
              [(ngModel)]="props.Value"

如果我添加这个错误

[ngControl]="props.id"

有什么需要从表单传递给子组件吗？
