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">
                    <li data-id="111" class="jieda-daan">
            <a name="item-1111111111"></a>
            <div class="detail-about detail-about-reply">
                         <a class="fly-avatar" href="">
                <img src="https://www.e-learn.cn/qa/data/avatar/000/00/00/small_000000037.jpg" alt=" 借酒劲吻你 ">
              </a>
              <div class="fly-detail-user">
                <a href="" class="fly-link">
                  <cite> 借酒劲吻你</cite>
                                             
                </a>
                
                <span>(楼主)</span>
            
              </div>              <div class="detail-hits">
                <span>2021-02-06 23:39</span>
              </div>

            </div>
            <div class="detail-body jieda-body photos">
              <p>          
<p>ngModel works if</p>

<ol>
<li>There is a form wrapped around it & textarea has a name attribute added to it.</li>
</ol>

<p>If you not you can use the following syntax to achieve the same effect</p>

<pre><code><textarea [value]="strVariableInComponent" (input)="strVariableInComponent = $event.target.value;">
