TableView Bug?

Hi everyone, I'm using Titanium 2.1.1, Android 4.1 on Windows 7. I'm trying to add a row to a tableView as the "return" event is fired, but when i add a new row it changes the title of the previous row and then displays the same title for each row. That's my code:

var win = Titanium.UI.currentWindow;
 var textField = Ti.UI.createTextField({
      borderStyle: Ti.UI.INPUT_BORDERSTYLE_ROUNDED,
      color: '#336699',
      top: 350,
      width: Ti.Platform.displayCaps.platformWidth, 
      height: Titanium.UI.SIZE, 
    });
 win.add(textField);
      var tableView = Ti.UI.createTableView({
    top: 0,
    width:Ti.Platform.displayCaps.platformWidth,
    height: 350*Ti.Platform.displayCaps.platformHeight/480,
    }); 
 /***** Beginning of the event******/
 textField.addEventListener('return',function(e){
 
 
   var row = Ti.UI.createTableViewRow({
            className: 'row',
        objName: 'row',
        touchEnabled: true,
        height: Titanium.UI.SIZE,
      width : Ti.Platform.displayCaps.platformWidth,                                                                            });
 
                                                       row.title = this.value;
                                                        tableView.appendRow(row);                                                   
                                                        this.value ='';
                                                         }); 
/**** End of the event*****/  
                                                      win.add(tableView);

Please did i do something wrong?
