If I do so, then the twitter widget is not regenerated (say the javascript is not running) if i change to "Recent" and the back to Main page. I have the twitter widget on homepage sidebar with this code:

<a class="twitter-timeline"  href="https://twitter.com/3malG" data-widget-id="507843649955041282">Tweets von @3malG </a>
<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+"://platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>

The Function seems not to run if I change the page on the nodebb topbar. Do I need to bind this code to some event, or what is required?

I use the current development edition for nodebb directly from github.
