reactive/model-driven in Angular 2

Question

In reference to tutorial here : http://blog.thoughtram.io/angular/2016/06/22/model-driven-forms-in-angular-2.html

this is how i am using reactive form in my application :

   <div class="login">
<form [formGroup]="form" (ngSubmit)="dologin(form.value)">
    <div class="form-group">
        <label for="username">Username</label>
        <input id="username" type="text" class="form-control" name="username" formControlName="username">

        <div [hidden]="form.controls['username'].valid || form.controls['username'].pristine"
        class="alert alert-danger"> Username is required.</div>
    </div>
    <div class="form-group">
        <label for="password">Password</label>
        <input id="password" type="password" class="form-control" name="password" [formControl]="form.controls['password']">
        <div [hidden]="form.controls['password'].valid || form.controls['password'].pristine"
        class="alert alert-danger"> Password is required.</div>
    </div>
    <button type="submit" [disabled]="!form.valid" class="btn btn-primary">Login</button>
</form>
</div>


export class LoginComponent implements OnInit {
    form:FormGroup;
    errorMessage:string;
    public isUserAuthenticated = false;

    constructor(private router: Router,private authenticationService : AuthenticationService,private httpService:HttpService,private formBuilder:FormBuilder) {
        this.form=formBuilder.group({
            username:['',Validators.required],
            password:['',Validators.required]
        });

    }

but somehow i am getting compilation errors as below:

Unhandled Promise rejection: Template parse errors: Can't bind to 'formGroup' since it isn't a known property of 'form'. (" ][formGroup]="form" (ngSubmit)="dologin(form.value)"> ][formControl]="form.controls['password']"> [ERROR ->] Username [ERROR ->]

I searched about NgControl providers , there i see that i am suppose to import the FORM_Directives but in Angular2.1 they have not mentioned anything about Form directives.

Please help me to figure out , what am i missing here.
