I'm actually working on this now for an app. The data is for the scores from a golf tournament. When I was that it loaded dynamically, I dug through all the requests using Chrome's developer tools. I was able to find the json that the page was using to load the data which turned out to be easier to deal with than scraping from html in the first place. So if you're running into this problem, try to find the url that they snag the data from in the first place.
