Using the code below will not add the query string 'section' to the link. The url adds just fine but what am i doing wrong with the query string?
@Html.Hidden("Url", Request.RawUrl)
@Html.Hidden("Query", sectionGroup.Term)
<a href="#" id="ajaxLink">@sectionGroup.Term</a>
<script>
  $("#ajaxLink").click(function () {     
    $.ajax({
      type: "POST",
      url: $("#Url").val(),
      data: { section : $("#Query").val() }
    }).done(function() {
    });
  });
</script>
    
url: $("#Url").val() + "?section=value",
