title: formGroup expects a FormGroup instance error in Angular2 form
body: <p>I am trying to create a basic form in Angular 2 on plunker but faced with the below error on Chrome Dev's Console:</p>
  
  <pre><code>VM8247:27 EXCEPTION: Error in ./App class App - inline template:1:12 caused by: formGroup expects a FormGroup instance. Please pass one in.
  
         Example:
  
  
      &lt;div [formGroup]="myGroup"&gt;
        &lt;input formControlName="firstName"&gt;
      &lt;/div&gt;
  
      In your class:
  
      this.myGroup = new FormGroup({
         firstName: new FormControl()
      });
  </code></pre>
  
  <p>Plus there are some other errors also which point to more or less the above error only. <strong>I came across other answers on SO related to this but most of them had typos in their code</strong>.</p>
