I'm using `textMask` node module to format the input tags for my form. I followed all instructions in the Git repository and the module woks perfectly. But when I try to run the component test it says: `Error: Template parse errors: Can't bind to 'textMask' since isn't a known property.`. Why I have this issue? This is my HTML template:

```html
 <input [textMask]="{mask: cpfMask}" type="text" id="inputCpf" required pattern="^[0-9]{3}\.[0-9]{3}\.[0-9]{3}\-[0-9]{2}$" name="inputCpf" [(ngModel)]="user.identification.value" #inputCpf="ngModel">

```

This is my **user.component.ts**:

```ts
@Component({
  selector: 'app-user',
  templateUrl: './user.component.html',
  styleUrls: ['./user.component.css'],
  providers: [RegisterUserService, TokenManagerService]
})
export class UserComponent implements OnInit {

  private user: User;
  private error: string;
  private id: string;
  private credential: Credential;
  public cpfMask = [/\d/, /\d/, /\d/, '.', /\d/, /\d/, /\d/, '.', /\d/, /\d/, /\d/, '-', /\d/, /\d/];

```

And this is my **app.module.ts:**

```ts
import { TextMaskModule } from 'angular2-text-mask';
@NgModule({
  imports: [
    BrowserModule,
    HttpClientModule,
    HttpModule,
    FormsModule,
    TextMaskModule,
    ...

```

I already visited the other few topics in SO that talk about this issue but their solutions didn't solved my problem.
