Android - Get info from tableview on tap.

I have a table view displaying data from a SQLite database. What I want to do is when the user taps on the table, a label will show the first column of the table view what is the item number. Here is my table view code:

var orderData = [];
 
var currentOrder = Titanium.UI.createTableView({
    top:320,
    bottom: 100,
    data: [],
    searchHidden:true,    
});

hdw.execute('INSERT INTO hdworder (_itemnumber,_desc, _qty) VALUES (?,?,?)',itemnum, descLabel.original, orderQty);
 
    orderData = [];
 
    var orderRows = hdw.execute('SELECT _itemnumber, _desc, _qty FROM hdworder ');
 
    while (orderRows.isValidRow())
    {
        orderData.push({title:orderRows.fieldByName('_itemnumber') + '      '  + orderRows.fieldByName('_desc') + '     ' + orderRows.fieldByName('_qty'), hasChild:true});
 
        orderRows.next();
    }
 
 
 
    if(orderRows.isValidRow()){
        result1 = {
            itemNumb: rows.fieldByName("_itemnumber")
        };
    };
 
    var hdwItemLabel = Titanium.UI.createLabel({
    color: '#999',
    text: result1.itemNumb,
    font:{fontSize:20,fontFamily:'Helvetica Neue'},
    top: 220, left: 300
});
 
    orderRows.close();  
    currentOrder.setData(orderData);
 
 
 
    win1.add(currentOrder);
    win1.add(hdwItemLabel);
    hdw.close();
});
