I am making a call to the Twitter API to get a list of tweets from a user and output them on a webpage. I am using iScroll.js to create a clean scrolling container for the tweets, but I need a way to call a function defined within a separate javascript file that initially created the scrolling area, after the Twitter API is finished with the call. This is the only way I can get the scrolling area to recalculate the actual height of the area. How could I make this happen?
