Update query in Sqlite plugin not getting updated in db using cordova

db.transaction(function (tx) {
                      tx.executeSql(" UPDATE tablename SET URL1= ? , URL2= ?   WHERE ID = ?",
                                    [url1, url2, id],
                                    function (tx, rst) {
                                        //do something
                                    },
                          onError = function (tx, e) {
                              //do something

                          })
                  });

even there was no error thrown, data was not updated in the db. once i tried the same from console, table got updated successfully. Am i missing something. Thanks in advance.
