I have a checkbox to show if a record is reviewed.
I have written the function to update the DB in the controller class using ajax.
How to call this function when checkbox is checked,Should this be called in onclick event?

If checkbox is unchecked ,the reviewed field in database should be 0 and If checkbox is checked ,the reviewed field in database should be 1
