Phonegap application issue

Phonegap application issue

I'm developing an app that on timeout update some data on db and
consequently change view on page relative to data. The app works perfectly
on chrome and firefox but when it run on device this data doesn't update
but on db is update. Maybe memory cache problem? This line maybe has
error?Maybe "$(window)"?
current_user.Set_last_activity();
$(window).bind('onload',setInterval(function(){current_user.Set_last_activity();},5000));
this.check_users_online() ;
$(window).bind('onload',
setInterval(function(){self.check_users_online();},5000));
in logcat was appeared this error:
