[flexcoders] DateFormatter function for dataGrid

[candysmate]

I'm trying to implement a DateFormatter function for a DataGridColumn
as a labelFunction:

private function formatDate(item:Object, column:DataGridColumn):String
{
        dateFormatted = new DateFormatter();
        dateFormatted.formatString = "DD-MM-YYYY"
        return dateFormatted.format(item[column.dataField]);
}

(MXML labelFunction="formatDate")

Not having any success right now. Any ideas please?
