formElement override not working in zf3

[jroedel]

I'm new to ZF3, but it looks like the formElement override isn't working. I'm using v3.2.2. I recently upgraded to ZF3 and I noticed that the form elements I was rendering with $this->formElement(xxx) weren't working.
I added the following configuration and it began to work:

'view_helpers' => [
    'aliases' => [
        'formElement' => 'TwbBundle\Form\View\Helper\TwbBundleFormElement',
    ],
],

I was making sure to load the TwbBundle module last, so it shouldn't be a configuration problem.
