Need Wordpress jQuery To Load After Ajax

I have a jquery that needs to be setup as a delegated event.  Or, in other words to load after ajax is finished.  This is beyond my abilities.  I did find this article but i don't know how to implement what they are suggesting since I am very new to jquery.  Here is the article - https://learn.jquery.com/events/event-delegation/

My site isn't live yet so I have restricted access to it.  If you need to see the site I will need your IP to whitelist you.  The more particulars and a screenshot of the site is on this question - https://www.experts-exchange.com/questions/29106720/Need-Jquery-Fixed-To-Post-Shipping-Message.html?anchorAnswerId=42609003#a42609003

I understand if you don't want to give your IP just give me the code to test and I will insert it.  Because this is wordpress I don't; want to hack the wordpress core files.

<script>
jQuery(function($) {
  // CHECK FOR UPS OPTION CHANGE
  $('body').on('change', '[name="shipping_method[0]"]', doPOCheck);

  // CHECK FOR ANY CHANGES TO ADDRESS OR SHIPPING CHECKBOX
  $('#billing_address_1,#billing_address_2,#shipping_address_1,#shipping_address_2,#ship-to-different-address-checkbox').change(doPOCheck);

  // THIS IS THE WORKHORSE  
  function doPOCheck ()
  {
    // Only proceed if we UPS is checked
    if ($('#shipping_method_0_132643').is(':checked') ) {

      // IF THE SHIPPING CHECKBOX IS CHECKED WE WANT THE SHIPPING
      // ADDRESSES OTHERWISE THE BILLING ADDRESSES
      if ($('#ship-to-different-address-checkbox').is(':checked')) {
        ad1 = $('#shipping_address_1').val();
        ad2 = $('#shipping_address_2').val();
      }
      else {
        ad1 = $('#billing_address_1').val();
        ad2 = $('#billing_address_2').val();
      }

      // DO THE PO CHECK
      if (hasPOBox(ad1, ad2)) {
        showPoError();
      }
      else {
        hidePoError();
      }
    }
	else {
	  hidePoError();
	}
  }
  
  function showPoError() 
  {
    var msg ='<div class="pobox-error woocommerce-NoticeGroup woocommerce-NoticeGroup-checkout"><ul class="woocommerce-error message-wrapper" role="alert"><li><div class="message-container container alert-color medium-text-center"><span class="message-icon icon-close"></span> <strong>UPS can not send to PO Box.</strong></div></li></ul></div>';
    if(!jQuery('.pobox-error').length) {
      $('#place_order').after(msg);
    }
  }

  function hidePoError(){
    $('.pobox-error').remove();
  }

  // This now becomes generic for billing and shipping
  function hasPOBox(ad1, ad2)
  {
    ad1 = ad1.replace(/[^A-Z]/gi,'').substr(0,5).toLowerCase();
    ad2 = ad2.replace(/[^A-Z]/gi,'').substr(0,5).toLowerCase();

    return (ad1=='pobox' || ad2=='pobox');
 }
});
</script>

Essentially, this code looks at the shipping addresses and if someone has PO Box in their address and they select UPS as a shipping method it produces a message.  This is because UPS won't ship to a PO Box.
