Title: Fix argument error in <= IE9

Was getting an argument error in <= IE9 until I change the call a bit to check for a function first. Looked like fn was actually 'true' instead of a function on first call... Weirdly enough I am not getting the same error on the swipejs home page but the slideshow doesn't actually finish going through all the slides, possibly another issue with <= IE9? See attached.
