javascript - jQuery function not working for dynamically added field -

-

i added group of fields dynamically. , assign class jquery function it. first row working fine when insert send row jquery function not working. insert dynamic field same class.

$(".catg").change(function(){   var classes = $(this).parents('.col-sm-3').parents('.input-group').attr('id');   alert(classes); });

you should use .on() create delegated events:

$(document).on('change', '.catg', function(){   var classes = $(this).parents('.col-sm-3').parents('.input-group').attr('id');   alert(classes); });
