Angular 2 - Assign value to checkbox using reactive form

Question

I'm trying to assign a value to a checkbox when checked and nothing (or false) when unchecked:

<input type="checkbox" [value]="key" [formControlName]="variable"/>

This doesn't work and the values are either true or false. Is it possible to assign a variable?

You could try this:

<input type="checkbox" (change)="$event.target.checked ? formGroupName.controls['variable'].setValue(key) : formGroupName.controls['variable'].setValue()" [formControlName]="variable"/>
