  Binds an existing control to a DOM element.
  
  # Example
  
  In this example, we bind the control to an input element. When the value of the input element
  changes, the value of
  the control will reflect that change. Likewise, if the value of the control changes, the input
  element reflects that
  change.
  
   ```
  @Component({selector: "login-comp"})
  @View({
       directives: [formDirectives],
       template: "<input type='text' [ng-form-control]='loginControl'>"
       })
  class LoginComp {
   loginControl:Control;
  
   constructor() {
     this.loginControl = new Control('');
   }
  }
  
   ```
  
  We can also use ng-model to bind a domain model to the form.
  
   ```
  @Component({selector: "login-comp"})
  @View({
       directives: [formDirectives],
       template: "<input type='text' [ng-form-control]='loginControl' [(ng-model)]='login'>"
       })
  class LoginComp {
   loginControl:Control;
   login:string;
  
   constructor() {
     this.loginControl = new Control('');
   }
  }
   ```
