.click() not working

.click() not working

I'm doing a site located at http://matjohnson.wc.lt/

On the supporters area of the page. I want to trigger the 2015 button so it filters those down, but the following code does not work :(

$('a:contains("2015")').trigger('click');
Now I know it finds the element because when I alert it out it shows the element value. But it just doesn't trigger the item.

Anyone got any help?
