updating custom object with returned value

Hi,
 
  I have a custom object Custom__c which has custom field Test__c. I have a custom button which calls(onclick javascript) a .net webservice returning some value that I want to update the Test__c with.
 
 Custom__c.Test__c = value didn't work. It says Custom__c is not defined.
 
I think I need to create a current instance of Custom__C class. But I don't have id for it. Can I create it on Name(field)? and how?
 
How should I go for it?
 
Thanks.

The javascript should be able to glean the ID via {!Custom__c.Test__c} if it's being called form a detail page from that object. 

Here's an example of both that in action, and also how I tie that into Apex code to do some other stuff.

This revolved around a combination of creating my own WebService in Apex, and then modifying my javascript to pass that variable to it.

Here's the Apex, note the bolded lines.  ":sig" refers to the variable I'm passing via javascript.

Code:
WebService static string reportFalseNegative(string sig){
  //set up our request object
  httprequest req = new httprequest();
  
  //and paramenters
  List<global__c> apikeyrequest = [select Value__c from Global__c where Name = 'defensiokey' limit 1];
  string apikey = apikeyrequest[0].Value__c;
  List<global__c> ownerurlrequest = [select Value__c from Global__c where Name = 'defensiourl' limit 1];
  string ownerurl = ownerurlrequest[0].Value__c;
  
  string apiurl = 'http://api.defensio.com/app/1.1/';
  string action = 'report-false-negatives/';
  string responsetype = 'xml';
  string body = 'owner-url=' + ownerurl +'&signatures=' + sig;
  string endpoint = apiurl + action + apikey + '.' + responsetype;
  system.debug(endpoint);
  
  //do the request
  req.setEndpoint(endpoint);
  Map<string, string> headers = new Map<string, string>();
  headers.put('content-length', '0');
  req.setHeader('content-length', headers.get('content-length'));
  req.setMethod('POST');
  req.setBody(body);
  system.debug(body);
  http http = new http();
  httpresponse auditCommentResponse = http.send(req);
  string response = auditCommentResponse.getBody();
  system.debug('\n\n---Response: ' + response + '---\n\n');
  
  //now we set the defensio__c object to trained = true
  defensio__c[] d;
  d = [select id, trained__c from defensio__c where name = :sig limit 1];
  d[0].trained__c = true;
  update d;  
  return response; 
 }

 
And here's the javascript.  I call this via an OnClick JS via a button on the detail page of this object.
Code:
{!REQUIRESCRIPT("/soap/ajax/10.0/connection.js")}
{!REQUIRESCRIPT("/soap/ajax/10.0/apex.js")}

var signature = "{!Defensio__c.Name}";
var result = sforce.apex.execute(
"defensio",
"reportFalseNegative",
{sig : signature});
alert("result: " + result);
