facebookConnectPlugin is not defined on second call (cordova 3.7, android)

I am building a cordova app, I integrated facebook sdk successfully using facebook plugin, able to call "facebookconnectplugin" only once without destroying app.

I am calling "facebookconnectplugin" at a example.html page, it works fine, now I am logged in. when i navigate to other page abc.html and after coming back to example.page it is showing me error "facebookConnectPlugin is not defined". js is present there.

when i destroy the app then again everything works fine on first time.
