Unchecked state not send to server

Dear support,
I have a problem,
In my ejcheckbox, when the state is checked, the value is sent to server, but when the state is unchecked, not only the value, but the property itself is not exist in the form data posted to server. The server need the property and value (false) in order to process the request.. Am I doing something wrong?

Thank you.

Hi Sugandi, 
Thanks for contacting Syncfusion support, 
We have analyzed your query (The server need the property and value (false) while post the form) and this is the natural behavior of checkboxes in HTML. If checked, then its value will be sent as parameter. If unchecked, then its value will not be sent as parameter in JavaScript. This behavior is used to distinguish checked state from unchecked state checkboxes in server side. 
To know more about this please refer the stack overflow link: http://stackoverflow.com/questions/3746678/force-a-checkbox-to-always-submit-even-when-unchecked
