How to update the backing property of an ngModel upon calling typeInElement?

[jfpicard123]

Here's the HTML

<input [(ngModel)]="user.username" name="username" required class="form-control" id="username" placeholder="Enter your username">

After this line of code (regardless if I run detectChanges or not)

spectator.typeInElement('myusername', username);

the backing property (user.username) is not updated.

How can this be achieved?

Thanks!

I just found ... I needed to import the FormsModule of course.
