Joomla website issue tooltip and cssmenu

On the website https://hasselts-fanfare.awebo.nl/agenda/ we have an issue with tooltip only with the list events loaded from jevents 3.6.6 and only on this page our cssmenu isn't working.
We get this issue: Uncaught TypeError: $(...).find(...).tooltip is not a function

We tried to disable all kind of plugins en set noconflict on or off, but no result. What can we do to resolve this?
