on_sent_ok deprecation

Hi,

I have seen that the on_sent_ok in the additional settings will be removed by the end of 2017.
https://contactform7.com/additional-settings/#javascript

Just making sure if i use the ‘wpcf7_ajax_json_echo’ filter I can still set $items[‘onSentOk’] and use it in a similar fashion.

Thanks
