Strange sqlite transaction behaviour

I have the following code (simplified):

function blub () {
  db.transaction(function (tx) {
    tx.executeSql("SELECT * FROM table", [], function (tx, rs) {
      for(var i = 0; i < rs.rows.length; i++) {
        insert_list_element_into_html_list();
      }
      updateList();
    });
  }, myMSG("error"), myMSG("success"));
}
function updateList() {
  $('ul').listview('refresh');
  $('ul').trigger('create');
}
function myMSG (msg) {
  return function (txt) {alert("MSG: "+msg+" "+txt.code)};
}

Now this function does alert "error", but when I comment updateList() it does alert success.

How is this possible? I thought that the transaction finishes independent of what the callback function contains, and the SELECT query should easily succeed.
