Why bootstrap modal callback fired when a collapse inside modal is opened

Question

I notice a strange behavior in bootstrap 2.3.2 where i have a collapse panel inside a modal . So when collapse is opened the modal callbacks(e.g.show,shown) are also fired. Cannot figure out why this is happening. Check here http://www.bootply.com/WHBcMZ6puA#

Is it a bug ?

Answer 1

That's a known issue. People wrote a solution, but it doesn't work.

$('#myModal').find('.accordion-toggle').on('hidden', function (event) {
    event.stopPropagation()
});    

It's namespacing problem, which was resolved in bootstrap 3 version. My recommendation, switch to bootstrap v3.
