title: How to add dynamically FormControl to FormGroup
body: <p>I have this <a href="https://plnkr.co/edit/sT94PRSy1yXSks6RxPhj?p=preview" rel="nofollow noreferrer">plunker</a>. I am creating form components dynamically, based on <code>model</code> (defined in <code>app.ts</code>), and cannot add </p>
  
  <p><code>formControlName = "name"</code> </p>
  
  <p>to the component. In the <code>control-factory.directive.ts</code> I add </p>
  
  <p><code>this.form.addControl(this.model.name, new FormControl());</code>, </p>
  
  <p>but how can I bind the value?</p>
