Angular 2 change event on every keypress

The change event is only called after the focus of the input has changed. How can I make it so that the event fires on every keypress?

<input type="text" [(ngModel)]="mymodel" (change)="valuechange($event)" />
{{mymodel}}

The second binding changes on every keypress btw.

I just used the event input and it worked fine as follows:

in .html file :

<input type="text" class="form-control" (input)="onSearchChange($event.target.value)">

in .ts file :

onSearchChange(searchValue: string): void {  
  console.log(searchValue);
}
