ngModel for textarea not working in angular 2

Question

I am trying to print json object in textarea using ngModel.

I have done following:

</script>
<ins class="adsbygoogle"
     style="display:block"
     data-ad-client="ca-pub-5408099190056760"
     data-ad-slot="7305827575"
     data-ad-format="auto"
     data-full-width-responsive="true"></ins>
<script>
     (adsbygoogle = window.adsbygoogle || []).push({});
</script>        </div>
      </div>
      
      <div class="fly-panel detail-box" id="flyReply">
        <fieldset class="layui-elem-field layui-field-title" style="text-align: center;">
          <legend>8条回答</legend>        </fieldset>

        <ul class="jieda" id="jieda">

<p>As per documentation [()] is for two way syntax sugar to remove the boilerplate. What event is being invoked at this? Irrespective, you can put a string output also alongwith the event in below code</p>

<p>Probably try the below code implemetation for your string output</p>

<pre><code>@Directive({
  selector: '[ngModel]',
  host: {
    "[value]": 'ngModel',
    "(input)": "ngModelChange.next($event.target.value)"
  }
})
class NgModelDirective {
  @Input() ngModel:any; // stored value
  @Output() ngModelChange:EventEmitter; = new EventEmitter() // an event emitter
}
</code></pre>
    </p>
