Well, as I'm still a bit asleep :-/ It cannot work as it is incompatible 
with how TYPO3 handles non-cached content.

As you know, non-cached content is stored as a special marker in the 
whole (cached) page. And this marker is replaced by the USER_INT content 
when the page is requested. As such, there is no way to use pageRenderer 
to add further information to the page header...

However the trick is to use

$this->response->addAdditionalHeaderData('
	<script type="text/javascript" src="/path/to/your/script.js"></script>');

The same for CSS, ...

Cheers
