I have a form that retrieves data from a stored procedure and I would like to manipulate the data to remove the ending '||' characters when displaying the data.  I have a function that is called onloadlookupfinished but this does not apply when the form is submitted and displayed.  I need the form to display as it does onloadlookupfinished.  Below is the code I have that is working, but need help with a script that will apply the change when the form is submitted.  

$(document).on('onloadlookupfinished', function () {
  $('#loadingscreen').hide();
  var comment = $('.comm textarea').val();
  comment = comment.replace(/[||]+$/, '');
  //alert(comment);
  $('.comm textarea').val(comment);
});

Display Correctly on load:

Default value is set to 'test || test ||' and I only want to remove the end set of '||'

After submission:

Thanks,

Nate
