You should listen to validation event on the first combo and load the list of items into the second one -

combo1.onControlValidated = function(text){
  var arrayOfItems = getItemsWithAjax(text);
  combo2.setItemText(arrayOfItems);
  combo2.setItemCount(arrayOfItems.length);
}

Thancks a lot Alex, but I have another question: How can i get the value of the item selected in combo1?.
It could be something like this?
combo1.onControlValidated = function(value){
  var result = getItemsWithAjax(value);
// resutl = [{city:{text:"havana",valor:1}},{city:{text:"varadero",valor:2}}];  
  combo2ItemText = new Array();
  combo2ItemValue = new Array();
  for(i=0; i<result.lentgh; i++){
      combo2ItemText[i] = result[i].city.text;
      combo2ItemValue[i] = result[i].city.value;
  }

  combo2.setItemText(combo2ItemText);
  combo2.setItemValue(combo2ItemValue);
  combo2.setItemCount(result.length);
}
