Correct jq_button_to_remote complete handler response var
Symfony docs claim that in the ‘complete’ callback you have access to the response as request.responseText.
From svn
* To access the server response, use ‘request.responseText’, to
* find out the HTTP status, use ‘request.status’.
This has not been my experience. When inspecting the variables in scope, I was only able to find, and subsequently access
XMLHttpRequest.responseText;
XMLHttpRequest.status;
