We have a form that totals a value in a table.  The calculation works fine as long as the user does not need to remove a row.  If they do, the total is not updated unless they click into the field with the res-sum class.  How can I change the code to update automatically?

$(document).ready(function () {
    $(document).on('blur change', '.res-sum input', sumtotal);
  
    function sumtotal() {
        var s = 0;
        $('.res-sum input').each(function () {
            s += parseNumber($(this).val());
        });
        $('.res-total input').val((s).toFixed(2));
    }
    function parseNumber(n) {
        var f = parseFloat(n); //Convert to float number.
        return isNaN(f) ? 0 : f; //treat invalid input as 0;
    }
})
