First, var data has to follow these rules (from jQuery API docs):
Data to be sent to the server. It is converted to a query string, if
not already a string. It's appended to the url for GET-requests. See
processData option to prevent this automatic processing. Object must
be Key/Value pairs. If value is an Array, jQuery serializes multiple
values with same key i.e. {foo:["bar1", "bar2"]} becomes
'&foo=bar1&foo=bar2'.

In your action you would check the request.vars for the keys of the
key/value pairs included in data, e.g. if
data= "id="+somevalue
then in action you obtain the value of key id as follows:
id=request.vars.id
BTW, to be useful you would probably need the callback inside your
$.ajax :
success: function(datain) { ... }
