Custom JS in Rise?

I have a leader board that I built in Storyline. It uses JavaScript to query the xAPI statements in a Learning Records Store and find the learner names and scores associated with the specific course, sort them and assign the values to Storyline variables. I'd like to use it in a Rise course. I exported the Rise course and added the xapiwrapper and my .js file that defines my function to the index.html file in the Rise course, The function gets defined, but it is never executed by the Storyline slide. Is this because the Storyline slide is inserted from Review 360, which doesn't really like to execute JavaScript? Has anyone else gotten something like this to work in Rise using JavaScript and Storyline variables?
