picker help

app type:mobile,android,titanium sdk:3.2.2.GA

Hello, I have a problem with my android application: I have more windows,in one window,i insert data into a sqlite database table,in an another window i have a picker which returns the data from a column of the same table.When i insert new lines in the table the data from the picker doesn't update.What should i do?How can i update the content of the picker? And another question:how can i insert a selected value from a picker into a table?

Here is the code:

var win1 = Titanium.UI.createWindow({
title:'Currency Prices',
backgroundColor:'#000'
});
 
 
function createCurrencyPicker() {
var currencyPicker = Ti.UI.createPicker(
{height :'40%',
selectionIndicator : true});
// populate the picker from the SQLite currencies
// Database file already exists so we need to use install,
//to copy it to the internal storage
var db = Ti.Database.open('client.db',
'clienti');
var data = db.execute
('SELECT  nume FROM clienti;');
var pickRow = []; var i = 0;
while (data.isValidRow()) {
pickRow[i++] = Ti.UI.createPickerRow
 
 
({title:data.fieldByName('counter')});
data.next();
}
data.close();
db.close();
currencyPicker.add(pickRow);
return currencyPicker;
};
 
//var vertLayout = Ti.UI.createView({layout:'vertical'});
//var stockList = Ti.UI.createTableView({});
var picker = createCurrencyPicker();
 
//vertLayout.add(picker);
//vertLayout.add(stockList);
win1.add(picker);
win1.open();
