rich:autocomplete not working richfaces 4.3

[amine8357]

I´m trying to implement a richfaces autocomplete component, the problem i have is that the autocompleteMethod is never called.

MBean:

public String getFormacode() {
  return testDto.getFormacode();
}

public void setFormacode(String formacode) {
  testDto.setFormacode(formacode);
}
public List<String> getToShow() {
  return testDto.getToShow();
}

public void setToShow(List<String> toShow) {
  testDto.setToShow(toShow);
}

public List<String> autocomplete(String prefix) {
  Map<String, String> map;
  List<String> listOfItems = new ArrayList<String>();
  try {
  map = testFacade.getFormacode(prefix);

  for (Entry<String, String> e : map.entrySet()) {
  listOfItems.add(e.getValue());
  }
  } catch (RemoteException | ServiceException e1) {
  e1.printStackTrace();
  }
  setToShow(listOfItems);
  return listOfItems;
}

When i debug, the getter getToShow and the function autocomplete are never called.

I am using richfaces 4.3.3

ps: in the log
