Sending dynamically generated javascript file

Background:

I have a servlet in which I dynamically generate javascript and put in a variable script. Then I set the content type of the response as I text/javascriptsend the script to the client:

resp.setContentType("text/javascript");
resp.getWriter().println(script);

Problem:

The browser loads the javascript file, but does not recognize the functions inside the file. If I create a static javascript file and use it instead, it works fine.

Question:

What needs to be done for the browser to treat the servlet response as a regular javascript file?

Thank you for your help.

        response.getWriter().write("function test() { alert('peek-a-boo'); }");
