Update: This seems to work, but calls loadevent() once for each step of a wizard that has been loaded. When I click to step two, it calls loadevent() twice, when I click to step three, it calls loadevent() three times. Any idea why that would be occurring?
Yes, that post is where I found the 'stepchange' event to begin with. My initial question was whether I could call 'stepchange' from $('body') instead of specifying a jquery selector for the wizard itself (trying to be as generic as possible). That seems to work, although it seems to fire once for each step that has been loaded.
