This works to trigger a Unbounce Conversion for buttons that do not navigate away but instead keep them on the same page

conversionClick.html

<script>

  window.trackConversion = function() {
    $('body').append('<iframe src="clkg/http/unbouncepages.com/blankpage/" style="display: none"></iframe>');
  };
  
  lp.jQuery(function($) {
    $('#lp-pom-button-11').click(function () {
      trackConversion();
    });
  });

</script>
