Dashboard switch widget question!

I used the dasboard from this link: http://www.homeautomationforgeeks.com/dashboard_setup.shtml1
The installation was OK. But only when I toggle a switch on my openhab webpage then the corresponding switch widget on the dashboard changed. If I toggle the switch on the dashboard side, I couldn’t see anything happen.
Can anyone show me how can I toggle switch on the dashboard side to control the switch on the openhab side?
Please, it would be a great help
Thanks in advance

Anyone can answer me please?

Knock knock?It seems this post is becoming faded . Is there any answer or idea, link refers to my problem? I’d be very thankful!
