there no need have click handler

var max = 3; var checkboxes = $("#collapseone input[type=checkbox]"); checkboxes.change(function(){     var current = checkboxes.filter(':checked').length;     $( "#col1" ).text(current) ;     checkboxes.filter(':not(:checked)').prop('disabled', current >= max); });

look @ this demo

your click handler result in registering no-of-clicks - 1 change handler executions
