I have to display some data that I receive from the server as json object like this

{"rowndx":"0","rows":"25","rowstotal":"100","rowsdata":[ 
["00","DEVICE001","T0_IHOME","1","***","1","10"], 
["01","DEVICE002","NO_DEVICE","1","***","1","10"],
["02","DEVICE003","NO_DEVICE","0","***","1","10"],
.....

Before displaying the received data in a table I would like to make changes where necessary adding units to the numbers or replacing the numbers with words (eg 0 ->OFF 1-> ON) To do this I have associated at the ajax option "success" my encoding function. In this case, however, remains always visible the message "Loading ..." and no other action is permitted. I moved my re-encoding procedure to the "complete" ajax option and this time it seems to work. But I did not understand what was my mistake and I do not know if my procedure can work. This is my table ajax configuration

    url      : "devtbl.json",
    mtype    : "POST",
    datatype : "json",
    postData : ......

    ajaxGridOptions: {
      type       : 'post',
      contentType: 'application/json',
      async      : false,
      complete   : DEVparse_serverdata,
      error      : function() { alert('Something bad happened. Stopping');},
    },

    jsonReader : {
      root        : "tablerows",
      page        : "currentpage",
      total       : "totalpages",
      records     : "totalrecords",
      cell        : "",
      id          : "0",
      userdata    : "userdata",
      repeatitems : true
    },

and my coding function

    function DEVparse_serverdata(js , textStatus) {

  var jsontablereply = {} ;
  var rowsxpage_int  = parseInt(UB.rowsxpage.DEVtable) ;
  var jsonreply =  jQuery.parseJSON(js.responseText) ;

  jsontablereply.currentpage  = "" + (1 + (parseInt(jsonreply.rowndx) / rowsxpage_int));
  jsontablereply.totalpages   = "" + parseInt((parseInt(jsonreply.rowstotal) + (rowsxpage_int-1)) / rowsxpage_int) ;
  jsontablereply.totalrecords = jsonreply.rowstotal;

  jsontablereply.tablerows = [] ;
  $.each(jsonreply.rowsdata, function(ndx, row) {
     var rowarray = [] ;

     rowarray[0] = row[0] ;
     rowarray[1] = row[1] ;
     rowarray[2] = row[2] ;
     rowarray[3] = row[3] ;
     rowarray[4] = row[4] ;

     switch (row[2]) {
       case "NO_DEVICE":
            rowarray[5] = "***" ;
            break ;

       case "T0_IHOME":
            rowarray[5] = "T=" + row[5] + "°C" ;
            break ;
     }
     jsontablereply.tablerows[ndx] = rowarray ;
  }) ; // each

  jQuery("#DEVtbl")[0].addJSONData(jsontablereply);
}

(I am a beginner with Jquery my coding style is poor)
