There's no generic jQuery way of achieving this because all the functionality of fullpage.js isn't included in the jQuery core. And jQuery does not cover events fired by plugins.
In the docs of fullpage.js is a section about the afterSlideLoad callback which gets "fired once the slide of a section have been loaded, after the scrolling has ended". There's also the afterLoad callback which will be "fired once the sections have been loaded, after the scrolling has ended". I don't know what fits your needs best. (Thanks to @Alvaro in the comments for the afterLoad
callback)
