Answer 1

Try

$(function() {
  $(".collapse").on('show.bs.collapse', function(e) {
    if ($(this).is(e.target)) {
      snippet.log(this.id)
    }
  })
});

Answer 2

you can try below code -

$('.accordion-toggle').click(function(){
       $(this).parent()
               .find("i.indicator")
               .toggleClass('fa-caret-down fa-caret-up');
  });

Try using shown.bs.collapse instead. http://www.tutorialspoint.com/bootstrap/bootstrap_collapse_plugin.htm
section The following table lists a few events that can be used with the collapse functionality.
