Angular testing form template and formControl

I am writing tests for our component, everything was working fine, until I started testing integration of the template with formControls. I am using same concept as Angular team in their test do. (https://github.com/angular/angular/blob/master/packages/forms/test/reactive_integration_spec.ts)

Anyway, I am struggling with Error: Expected 'John' to equal 'Thomas' in the last expect. Here is my code:

it('should change formControl value when value inside the input is changed', () => {
    hostComponent.formConfig = {mode: 'write'};
    const control = component.updateForm.get('surName');
    hostFixture.detectChanges();

    // model -> view
    const input = hostFixture.debugElement.query(By.css('#surName'));
    const element = input.nativeElement as HTMLInputElement;
    expect(element.value).toEqual('John');

    element.value = 'Thomas';
    element.dispatchEvent(new Event('input'));

    // view -> model
    expect(control.value).toEqual('Thomas'); // This expectation is failing
  });

Is anybody here able to help me please? I have tried almost everything and this test is 95% identical to the Angular one.
