I have set following configurations in admin ;
Enable JavaScript Bundling: Yes
Merge JavaScript Files: Yes
Minify JavaScript Files: Yes
and have done similar with CSS.
When I test my site with http://www.webpagetest.org I still see multiple JavaScript Requests - see screenshot. The domain is http://www.extenderstore.com.au - why is this occurring?
According to the Magento documentation, some JavaScript files are excluded from JavaScript Bundle file.
Moreover you must be in production mode.

You can fine tuning the exclude list in your custom theme :
<vars module="Js_Bundle">
<var name="bundle_size">1MB</var>
</vars>
<exclude>
