TableView Row Count?

hi there, i have tableview which is loading new data while pulling down. Everything just fine it works but i want to make it total data === table.rowCount alert and i am not sure that setTimeOut function is ok? is there anyway to make it if the new data loaded delete the loadingrow? this is the kitchensink dynamic scrolling tableview example which is pulling data from a json file.

here is my code:

var win = Ti.UI.currentWindow;
 
var limitstart = 0;
 
var tbl_data = [];
 
var lastRow = 10;
 
var total_records = null;
 
 
 
 
 
var xhr = Titanium.Network.createHTTPClient();
 
xhr.onload = function() {
var jsonObject = JSON.parse(this.responseText);
                total_records = jsonObject.total;
 
                Ti.API.info("Total Records:"+total_records)
                for (var i = limitstart; i < lastRow ; i++){
                                var row =  Ti.UI.createTableViewRow({
                                    backgroundColor:'#494949',
                                    className:'myClass',
                                    height:50
 
                                });
                                var label = Ti.UI.createLabel({
                                    text:i+"-Ba?l?k:"+jsonObject.sorgu[i].baslik,
                                    left:20,
                                    font:{
                                        size:10
                                    },
                                    color:'#FFF',
                                    top:0,
                                    width:280,
                                    height:45
                                });
 
 
                                row.add(label);
                                tbl_data.push(row);
 
                        }
