title: How to use 'ngModel' with form control name?
body: <p>I have 2 textareas, if the user enters or inserts the value, need to update on other textarea field as well.</p>
  
  <p>My be I can use the <code>change</code> function to do that, But I tried to use the ng-model with the control name. getting error. how to fix this? or can't we use the control name with ngmodel to gathered?</p>
  
  <p>here is my textarea:</p>
  
  <pre><code>&lt;textarea name="control-name" [(ngModel)]="control_name_text" formControlName="ControlName"  [ngModelOptions]="{standalone: true}" cols="85" rows="5" placeholder="Enter Control Name"&gt;&lt;/textarea&gt;
  </code></pre>
  
  <p>another one:</p>
  
  <pre><code>&lt;textarea name="pageUrl" [value]="control_name_text"  cols="85" rows="5" placeholder=""&gt;&lt;/textarea&gt;
  </code></pre>
  
  <p>i have declared the <code>control_name_text</code> - in ts file as well. getting error as:</p>
  
  <pre><code>Can't bind to 'ngModelOptions' since it isn't a known property of 'textarea'.
  </code></pre>
  
  <p>any help?
  Thanks in advance.</p>
