Angular 2 get Input element value

Question

how to get html element value using ionic 2

Below my html code

 <div class="messagesholder" *ngFor="let chat of chatval | orderby:'[date]'" >
   <div *ngIf="chat.sender == currentuser || chat.receiver == currentuser">
    <div  *ngIf="chat.date" style="text-align: center;" >
           <p style="font-size:9px;" id="amount" #amount>{{chat.date | amDateFormat:'LL'}}</p>
           <input #myname [ngModel]="range" (ngModelChange)="saverange($event)"/>
         <input #myname type="text" value={{chat.date}}>
    </div>
   </div>
   <div class="message" *ngIf="chat.sender == currentuser || chat.receiver == currentuser" [ngClass]="{'me': currentuser == chat.sender}">
          <div class='image' *ngIf="chat.path" >
            <img *ngIf="chat.path" [src]="chat.path"/><br>
            <span *ngIf="chat.path_text">{{chat.path_text}}</span>
            <span style="font-size:9px;">{{chat.date | amDateFormat:'hh:mmA'}}</span>
          </div> 
           <div *ngIf="chat.message_text">
           <span>{{chat.message_text}}</span>
           <span style="font-size:9px;">{{chat.date | amDateFormat:'hh:mmA'}}</span>
           </div>
    </div>

Below my ts file

import { Component,Inject,ViewChild,ElementRef,AfterViewInit} from '@angular/core';

export class ChatPage implements AfterViewInit {
  @ViewChild('myname') input:ElementRef; 
  constructor(public modalCtrl: ModalController,public navCtrl: NavController) {}
   ngAfterViewInit() {
    console.log(this.input.nativeElement.value);
    }
  }

Same date values are repeated.I want same date values are not repeated.

Because I will check two variable.

so I need chat.date value.because i binded the value of input.But i cannot get the value of input element.

i am getting this error

Cannot read property 'nativeElement' of undefined

How to fix this issue.or any other way to find slutions.

Thanks

I created a plnkr link: https://plnkr.co/edit/49TEP8lB4lNJEKsy3IDq?p=preview

It works for me so probably you may want to create your own plnkr so ppl can help

export class ApiDemoApp{
  root = ApiDemoPage;
  @ViewChild('myname') input:ElementRef; 
  constructor() {
  }
  ngAfterViewInit() {
  console.log(this.input.nativeElement.value);
  }
}
