title: JSONP function call issue
body: <p>i set up a webservice thats cross domain and needs to be contacted via json with padding 
  on a simple jquery codeline like this, i am successfull getting back json data.</p>
  
  <pre><code>$.getJSON("http://server/series/hist?jsonp=?", function(data){
   console.log(data);
  });
  </code></pre>
  
  <p>the webservice, will wrap the result in a function, whenever "jsonp" exists within in the url.
  for those cases i used a default function name like: </p>
  
  <pre><code>myfunction({"a":1})
  </code></pre>
  
  <p>jquery helps me out here, and trys to call the function, that isnt existing ("myfunction()"). what i am trying to achieve instead is a simple call of the callback function (see above), to handle the data locally.</p>
  
  <p>can you point me in the right direction? </p>
  
  <p>thank you</p>
