What's wrong here?

template: 

<drr-person (isMinorEmittor)="setPersonIsMinor($event)" [group]="requesterForm" [required]="true" ></drr-person>

ts:

ngOnInit() {

    if (!this.required)
        this.personForm.addControl("nationalnumber", this.fb.control("", [Validators.minLength(11)]));
    else
        this.personForm.addControl("nationalnumber", this.fb.control("", [Validators.required, Validators.minLength(11)]));

}

Throws:

EXCEPTION: Error in ... caused by: Expression has changed after it was checked. Previous value: 'false'. Current value: 'true'.
