grunt bower-install does nothing? - gruntjs

Question

I'm very new with grunt/bower. What I'm trying to do is install dependencies on my application and have them injected into my source directly.
I do something like:
bower install socket.io-client
followed by;
grunt bower-install
Since I want the newly installed dependencies in my index.html, and indeed my grunt serve shows:
>> File "app/index.html" changed.
... Reload app/index.html ...
Completed in 0.000s at Wed Mar 19 2014 15:06:11 GMT+0100 (CET) - Waiting...
And then I check my index.html file to see that nothing has changed. Also, I can check on my browser console that io isn't available.
What am I doing wrong here? Doesn't grunt bower-install work out of the box, or do I need to change it? What is grunt bower-install doing that triggers a change on the grunt serve output?

You need to be sure to save your installed dependencies to bower.json (bower install --save __). grunt-bower-install uses that file to know what dependencies your app has.
