title: using reCAPTCHA with ajax....javascript loading problem
body: <p>I trying to implement reCAPTCHA in one of my forms,...but i am using ajax as the submission. (More specifically the prototype ajax.updater)</p>
  
  <p>Once I submit and error check my form I try to load the reCAPCHTA widget thingy (in my updated div element) which basically just calls a javascript file like so:</p>
  
  <pre><code>&lt;script type="text/javascript" src="http://api.recaptcha.net/challenge?k=6Le6SwUAAAAAAIWm8wCRFd8SrI-H0R1Yx4Tkw2Ks"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>However the JS file is not being read?...and i've tried all combination of evalScripts:true and evalJS:'force' etc. in the ajax.updater.....however i don't think I have a very good understanding of why the js file isn't processing :(</p>
  
  <p>If anyone can shed some light on this issue I will be very appreciative.</p>
  
  <p>Thanks, Andrew</p>
