Each time a new pagepart was added to a page, several javascript modules got reinitialised, even when they had nothing to do with this pagepart.
This feature makes it possible to just reinitialise one or more specific modules. This way, it is also possible to reinitialise modules which aren't default in the bundles.
This is an example of how you can trigger a reinitialise. Give the element a 'js-reinit' class and in the data attribute 'data-reinit-js' you can set the modules that need to be reinitialised for this pagepart.
It is important that the module has a public reInit function, because this is the function that will get triggered when the pagepart is added to the page.
