Note: The bootstrap docs now use the second example.
For bootstrap-switch 3.0 release candidate the event previously given as an example on the official page was:
$('#switch-change').on('switchChange', function (e, data) {});
It doesn’t get fired!
Solution – use this instead :
$('#switch-change').on('switchChange.bootstrapSwitch', function (event, state) {});
where state parameter is the value of the checkbox.
