Your action class is not saving the form if it's valid. You should save and redirect if the form is valid:
if ($this->registration_form->isValid())
{
$this->registration_form->save();
$this->redirect('registration/thankyou');
}
If you need the form value on the next page, don't pass them in url, but flash instead:
$this->getUser()->setFlash('registration_form', $this->registration_form->getValues());
