My hackaround solution:

// Global Variable in my common.js
var loadCompleteEx;

// set defaults
$.extend($.jgrid.defaults, {
     datatype: 'json',
     height: "100%",
     ...
     loadComplete: function () {
         if ($("#grid").getGridParam("reccount") === 0)
            $("#empty-grid-message").show();
         else
            $("#empty-grid-message").hide();

         // if loadCompleteEx is defined, call it at the end of loadComplete
         if (loadCompleteEx)
             loadCompleteEx();
      }
}

// In my specific page js
loadCompleteEx = function () {
    // Do more stuff after load completes
};

Works like a charm...is there any bad practice in here?
