[TIMOB-1012] table view row painting issue when changing row data

when you click a row the bg color for the row is changed and hasCheck is set to true. if you click it again, the row bg color goes back to white and hasCheck is false. the issue is that some rows become grey when not clicked - seems to be row repaint issue. here's the code:

var win = Titanium.UI.createWindow();

//win.row = null;

    var inputData = [ 
        {title:'Children', leftImage:'icons/children.png', backgroundColor:'#fff', test:'children.js', header:'C'},
