Comment:

 exit; is required to prevent anything else from being executed.

 You need to decide how you want data to be returned, which is simply
 echo'd. Generally we use die('1') for success, die('0') for failure,
 die('-1') for insufficient permissions. Then you can check for the strings
 1, 0, and -1.

 Or, you could return the post ID, if that's what you need.

 You can also return the data using json_encode(). Or, you can use the
 WP_Ajax_Response class.

 You can also return JS directly to execute it, etc. It's up to you on how
 you wish to implement your ajax call.
