I want to measure what parts of the Carousel people are clicking on
the most. But when I make a selector on my forward and back buttons,
and try to ping my reporting tool whenever they're clicked, the
animation on the carousel gets broken. Is there a way to wait until my
Carousel is done rendering the movement before I call the measurement
function?

I tried:

galleryCarousel.subscribe("change", function() {alert("now I'll ping
my reporting server")});

but it tells me that galleryCarousel.subscribe is not a function. I'm
not really sure what I'm doing with subscribe--it's just a thing I've
seen around for sequencing.

I'd love some help if you can see what I'm doing wrong. thanks!
