Clicking Ember link-to helper link does nothing

I have a route called notes. I am loading a set of note objects for this route. However, I have links using link-to helper that are supposed to load the notes route with adding a few query parameters.

The code I have is:

the links get rendered correctly, and the route correctly gets displayed as localhost:4000/notes?tagId=xxx. These links are on the same page which is localhost:4000/notes. Clicking on these links does nothing. Can someone throw some light at this?

Thank you
