How do I make lens filters work?

Question

I have created an RSS feed lens based on unity-lens-python, but I cannot get the filters to work. I've also tried the original unity-lens-python and the filter does not work in that lens either.

My lens can be found on my Google documents page, and it would be great if someone could have a look into it.

Make sure you connect to the "filters-changed" signal and update your results when it's fired. For an example see the one-hundred-scopes project where this is used. ( http://bazaar.launchpad.net/~davidc3/onehundredscopes/desura/view/head:/src/unity-scope-desura#L34 )
