Additionally filter buttons won´t update the URL hash (see my JSFIDDLE)

Question

sadly i am not that good with JS to find out what is wrong I am trying like it says on this page

http://isotope.metafizzy.co/demos/hash-history.html#filter=*&sortAscending=true

If i click on the first filter the result is ok but as soon as i select another filter the filter before gets removed by the 2nd.

Please see my Fiddle here:

You simply forgot the <div id="options"> bit.
