im not using the getter on the view!

im trying to trace a getter in the command.. just to know how to retrieve some value from the value object, through the proxy...
i feel that im still little confused about VO and PROXY relationship...
something between the getter... and how to access the imported VO in proxy to retrieve the data.. since its initializaed on the view as you saw in the bindable...(new Valor(0))...
take a look my proxy
package com.drm.Login.model
{
import com.drm.Login.ApplicationFacade;
import com.drm.Login.model.vo.Valor;
import org.puremvc.as3.interfaces.*;
import org.puremvc.as3.patterns.proxy.Proxy;
/*
testando um proxy
*/
public class TesteProxy extends Proxy implements IProxy
{
public static const NAME:String ="TesteProxy";
public function TesteProxy()
{
//the vo is initialized on the view with the 0 value...
//is bindable... so it automatically update de label.text
//its work fine
super (NAME);
}
public function acrescentaNumero(valor:Valor):void{
//the command pass to here.. the valor object..
//then adds a number to it... hmm i really updating the VO?
//i guess that yes its..
//it just works.
valor.valor++;
sendNotification(ApplicationFacade.ACRESCENTOU_NUMERO,valor);
}
public function get valor( ) : Valor {
//i cant figure out how to do this...
trace (data); //but whats data?? hehehe
//i know that must be on the proxy constructor
//but... im not initializing in the proxy!
//how can i access it?
//im little confused.
//can help me please?

return data as Valor;
}
}
}
