title: Bind input to only one text input in angular
body: <p>There is a scenario where I use ngfor and adding the text box for each iteration. When I type anything in the text box it binds to every text box but I want to give input to that text box only which I click to enter a value.</p>
  <pre><code>&lt;div class=&quot;comment&quot; *ngFor=&quot;let comment of blog.comments&quot;&gt; 
    &lt;p&gt;posts...&lt;/p&gt;
    &lt;input type=&quot;text&quot; [(ngModel)]=&quot;newComment.content&quot; [ngModelOptions]=&quot;{standalone: true}&quot;&gt;
  &lt;/div&gt;
  </code></pre>
