JSON応答から返された新しいデータでwin1.title(ラベル)を更新する必要があります。コンソールのwin1.title値で印刷できますが、新しい値を割り当てることができません。

//HERE I NEED TO UPDATE win1.title with title returned by JSON
/*
if a print win1.title it works correctly.
console.log(win1.title);
but if I try to assign data to win1.title nothing happens, even a error!
