I´m triggering an alert by jQuery with Joomla.renderMessages. The alert comes up, but won´t close when I press the close button!?

I´m using a custom template, I´ve made from scratch

I´ve search for answers without luck. according to this - https://docs.joomla.org/Display_error_messages_and_notices, it dosen´t seem like I need anything included in the template files, but I have the feeling that I need some javascript to make it work?

Joomla.renderMessages({'success': ['Du kan ikke gemme en tom note']});
