[TYPO3-english] TYPO3 6.2.x: adding extra fields to tx_news not showing up in front-end

[Bert Hiddink [BENDOO e-work solutions]]

Hello,

I followed this example 
<https://t3brightside.com/blog/article/extending-extnews-with-a-fal-compilant-audio-and-customized-youtube-video/>

...to add some extra fields to tx_news, it even includes a sample extension.

In the backend, the added fields show up and I can add/edit values. 
However, when trying to show the values in Fluid with:
{newsItem.txNewscustomYoutube}
...no output is shown.

Is this an outdated approach? Any help?

Thanks in advance!
Bert

<?php

    'label' =>
