    type:'GET',
    cache: false,
    success: function(result){
      $("#decContainer").show().html(result);
      var decHeading = $("#decContainer h2:first");
      /* set tabindex="-1" so the heading can receive keyboard focus */
      decHeading.attr('tabindex','-1');
      setTimeout(function(){ 
        /* move focus to the heading after a delay of 1 second */
        $("#decContainer h2:first").focus();
