How to set querystring or parameters dynamically with iron-router?

Question

I've seen this thread on how to append/modify query parameters without duplicating, but I can't make it work.

I have a page in my Meteor application that lists items and allows filtering. I would like the filtering to be URL-based, so every change to a filter should reflect in the URL. I use iron-router to then update the subscription accordingly.

For some reason, I can't modify the querystring though. This code doesn't trigger any action if called from a Template.templateName.events(...):

# valuePairs = ["foo=bar", "bar=foo"]    
newUrl = Router.current().route.path {}, { query: valuePairs.join('&') }
Router.go newUrl

But if I call Router.go(newUrl) from the commandline, the expected result happens, i.e. the URL updates.

Is there another, preferred method to modify the query?

If not, how can I make above code work?

UPDATE - I just found that after running the event, if I go back in my browser history I can see the correct URL. It looks like something (?) triggers another page load to go back to original page.

Just based on

Do you suppress the actual link event? An <a href='#'> would flip flop you right back.

Template.tempyTheTemplate.events({
    'click awesomeButton': function() {
        // URL stuff
        Router.go(magicURL);
        return false;  // <-- suppresses the event
    }
});
