jquery getScript problem with Internet Explorer 8

I've this script

$.getScript('page.asp?t=' +timestap);

page.asp generate this:

MyFunction({
  "result" : {
    "error" : false/true,
    "delete" : false/true,
    "data" : 'escaped html data'
  }
});

with Fir开发者_JAVA技巧efox it works like a charm, but with Internet Explorer result.data is empty

any help?

Is the content-type of page.asp set to server "text/javascript"?
