If it finds this key, the post view is an AJAX-JSON request and the key VALUE represents
 a function responsible for handling the response.
        
These ajax enabled post view functions must start with the prefix
ajax__ followed by the VALUE of the post_view_key.

Example:
    so lets say we find in the POST dictionary

Than there should be a function called   'ajax__change_parameter'
