Here\'s a fiddle with a working Bootstrap carousel. http://jsfiddle.net/jeykeu/5TDff/
And here\'s the official documentation which tells nothing about event usage. h
For Bootstrap 3 implementations :
Before event
$('#myCarousel').bind('slide.bs.carousel', function (e) { console.log('before'); });
After event
$('#myCarousel').bind('slid.bs.carousel', function (e) { console.log('after'); });
