Angular input events not triggered with ngModel binding

Question

I am currently working on a small angular project and have a problem with input events.

I have following code:

<select (change)="onSelect($event.target.value)" >   
    <option *ngFor="let option of options" [value]="option.id">{{option.name}}</option> 
</select>

This is working fine and well. But I wanted to change it to following:

<select (change)="onSelect($event.target.value)" [(ngModel)]="selectedItem">
    <option *ngFor="let option of options" [value]="option.id">{{option.name}}</option>
</select>

Now after this the change event is not triggered anymore. I also tried [ngModel] and (ngModelChange) and a lot more. But as long as there is something with ngModel and a binding in it the events do not trigger anymore.

All my Angular stuff is in version 5.1.2, the CLI in 1.6.2

Does anyone know why Angular has that behaviour? Greetings and thank you.
