title: how to trigger dajaxice.core.js to be updated with ajax.py
body: <p>I am using django-dajaxice, and after I tried the example, the file of <code>dajaxice/dajaxice.core.js</code> has loaded some functions from <code>myapp/ajax.py</code></p>
  
  <p>But the strange part is that, if I update this ajax.py in myapp folder, the js file is not updated with it, no matter I add a function or change the name of it, or delete any function in ajax.py.</p>
  
  <p>The strange thing is that only sayhello works, ANY other function name doesn't work. Is it anything related with .pyc files? I deleted all the pyc files and got the same error.</p>
  
  <p>Or in Python3, I shouldn't use dajaxice? But why sayhello works?</p>
