How to validate on submit?

[Almis90]

Let's say I have the following code

<form>
  <input type="text" [(ngModel)]="model.email" name="email" #formControl="ngModel" email />
  <span *ngIf="formControl.hasError('normalEmailRule')">Is not a email</span>
</form>

When I type something it shows the error, but I also want to show the error when the user clicks on submit.
