How to make javascript enable in multiple bootstrap modal?

I have multiple remote modals with auto calculation in them. They're the auto calculation form that a user must select the number from drop down.

The first modal is working very well. But it's not on the later on. The javascript code is usually embed in the remote file separately.

But when any modal was triggered. The rest of modal is not working in auto calculation.

Javascript (embedded each remote file)

    //clear bs
    $('body').on('hidden.bs.modal', '.modal', function() {
      $(this).removeData('bs.modal');
    });
  //currency format
  function addCommas(nStr) {
    nStr += '';
    x = nStr.split('.');
    x1 = x[0];
    x2 = x.length > 1 ? '.' + x[1] : '';
    var rgx = /(d+)(d{3})/;
    while (rgx.test(x1)) {
      x1 = x1.replace(rgx, '$1' + ',' + '$2');
    }
    retu x1 + x2;
  }
  //calculator
  $(document).ready(function() {
    //transfer charge
    $('#total').text('0');
    $('#xChrg').click(function() {
      if ($(this).is(':checked')) {
        $('#total').text('0');
        $('#p1').val('3500');
        console.log('3500');
        $('#p2').val('2100');
        $('#bk_rem').fadeIn();
        $('#n1,#n2').val(0);
      } else {
        $('#total').text('0');
        $('#p1').val('3500');
        $('#p2').val('2100');
        $('#bk_rem').fadeOut();
        $('#n1,#n2').val(0);
      }
    });
  });

  $('#n1,#n2').change(function() {
    $('#total').text('฿' + addCommas($('#p1').val() * $('#n1').val() + $('#p2').val() * $('#n2').val()));
  });
