Get data from ajax response

At school, I need to develop a Twitter client with ASP.NET.

In the application, I have a list of tweets with a link to delete. This link is created using the Ajax.ActionLink () helper, and I specified a callback function for the OnSuccess event.

This link is fine: the action is being executed, the callback is being triggered, BUT I cannot access the data sent in the Ajax response.

The callback receives only one argument. Here is a dump of this object:

>> Sys.Mvc.AjaxContext
$0: 0
$1: null
$2: Sys.Net.XMLHttpExecutor
$3: Sys.Net.WebRequest
$4: null

Where is my text answer? I know the answer has content (according to the Chrome developer tools) and I really want to access it.

Bonus: can the Ajax client automatically parse the response as JSON (the action returns JSON correctly using the JSON method)?

Thank!;)
