fire input onchange event after click on button tag

I am doing calculation with function ("update_total") by "onchange" event of input tab number.
it is working fine. no any issue.

when i am using jquery plugin "Nice-Number" for showing plus(+), minus(-) button.

onchange event of input tag is not getting fire. because mouse get clicked on plus(+) or minus(-) button.

therefor i am not getting ("update_total") total value.

please help how to resolve this issue.

$(function() {

function update_total(spineerid, product_price, totalid) {
  spineerid = '#' + spineerid;
  totalid = '#' + totalid;

  var qty_count = $(spineerid).val();
  var total = product_price * qty_count;
  $(totalid).html(total + '/-'); // display total
