Translate yes/no buttons in logout dialog

The yes/no buttons in logout dialog are not translatable.

to solve this issue I used:

autologout.js
...
      var myButtons = {};
      myButtons[Drupal.t('Yes')] = function()  {
        $(this).dialog("destroy");
        clearTimeout(paddingTimer);
        refresh();
      };
      myButtons[Drupal.t('No')] = function()  {
        $(this).dialog("destroy");
        logout();
      };
...
      function dialog() {
...
      buttons: myButtons,

clear cache, translate as usual.
