hash urls

I am obviously missing something here but my (very old) code had:
     hp.bind = function () {
            ko.applyBindingsToNode(this.element, {
                attr: {
                   'href': pager.Href.hash + this.path()
                }
            });
        };

but this is no longer in version 1.  I found I had to add it back in to get the hash in my page-hrefs
