Router.go does't work as it is supposed to

This is my code

Template.contactus.events({
      'submit #contactForm': function (e, t) {

        e.preventDefault();
        // Session.set('toAddr', "myEmail");

        // Session.set('subject', t.find('#subject').value);
        // Session.set('fromAddr', t.find('#email').value);
        // Session.set('content', t.find('#message').value);

        // Metoer.call('sendEmailF', Session.get('toAddr'), Session.get('fromAddr'), Session.get('subject'), Session.get('content'));

        Router.go('/aboutus');


      }
});

I commented out the code to test the Router.go() function, and all what it does is refreshing the current page instead of directing me to aboutus page.

What am I doing wrong here?
