Filter does not work in the demos with Chrome

I tried the filter demo example.

I did not work with my Chrome browser on OSX. So I started to dissect the code in filters.html.

I ended up removing .toLowerCase() in the code on line 95:

return d.name.toLowerCase().indexOf(newVal) !== -1 || !newVal;

Now it works but you have to use upper and lowercase letters.

So if anyone else has problem to get the filter demo to work this could be the solution!
