angular 2 ng-bootstrap datepicker popup

但是,如果我添加了多个datepicker输入标记,则只有一个正在工作.以下是我创建的代码.我尝试将#d更改为#d1和#d2(也更改了toggle()部分)并且页面吐出错误.

<div class="input-group">
    <input class="form-control" placeholder="yyyy-mm-dd" name="dp" [(ngModel)]="newItem.EndTime"  ngbDatepicker #d="ngbDatepicker" required>
    <div class="input-group-addon" (click)="d.toggle()" >
        <i class="fa fa-calendar" aria-hidden="true"></i>
    </div>
</div>

<div class="input-group">
    <input class="form-control" placeholder="yyyy-mm-dd" name="dp" [(ngModel)]="newItem.StartTime"  ngbDatepicker #d="ngbDatepicker" required>
    <div class="input-group-addon" (click)="d.toggle()" >
        <i class="fa fa-calendar" aria-hidden="true"></i>
    </div>
</div>

我还试图用一个组件包装它,它允许我有不同属性的多个datepicker实例.但是,它似乎没有将值传递回父组件.

new.campaign.html

<div class="row col-md-12 col-lg-12">
    <div class="col-md-4 col-lg-4">
        <label for="campaignStartTime">Start Time</label>
        <datepicker-popup [(model)]="newItem.StartTime" (modelChange)="updateDate($event)" [required]="true" id="campaignStartTime"></datepicker-popup>
    </div>
</div>

日期选择器,popup.component.ts

import {Component,Input,Output,EventEmitter} from '@angular/core';
    @Component({
selector: 'datepicker-popup',templateUrl: 'app/campaign/datepicker-popup.html'
    })
    export class DatepickerPopupComponent {
    @Input()
    model:any;
    @Input()
    id:string;
    @Input()
    required:boolean=false;
    @Output()
    modelChange: EventEmitter<any> = new EventEmitter();

    constructor(){    }
    updateModel(){
    let date = this.model;
    date = '12/22/2016'
    this.modelChange.emit(date);
    }
    }

日期选择器,popup.html

<div class="input-group">
    <input class="form-control" placeholder="yyyy-mm-dd" name="dp [(ngModel)]="model"  (change)="updateModel()" ngbDatepicker #d="ngbDatepicker" required>
    <div class="input-group-addon" (click)="d.toggle()" >
        <i class="fa fa-calendar" aria-hidden="true"></i>
    </div>
</div>

有人能指出我正确的方向来解决问题吗？
