Calculate sum of dynamically adding input fields with jquery

I've a form where i am calculating sum of amounts. Rows are dynamically generated with jquery clone();

This code is calculating sum of rendered rows not the new created rows

 $(document).ready(function(){

        $('.datepicker').datepicker();

        var $inst = $('.inst_amount');
            $inst_form = $('.inst_form');
            $total_amount = $('#total_amount');
            $total_price = $('#total_price');
            total = 0;

        $.each($inst, function(index, val) {
            var val = ($(this).val() == "") ? 0 : $(this).val();
            total = total + parseFloat(val);
        });
         $total_price.html(Math.round(total));
         $total_amount.val(Math.round(total));


        $(document).on('blur','.inst_amount', function(){
            var total = 0;
            $.each($inst, function(index, val) {
                var val = ($(this).val() == "") ? 0 : $(this).val();
                total = total + parseFloat(val);
            });
            console.log(total);
            $total_price.html(Math.round(total));
            $total_amount.val(Math.round(total));
        }); 
});
