One of my `{{link-to}}` helpers is triggering a page reload. How can i figure out what is causing that page to reload completely?

The link is supposed to send me back to the index page / from the /:id path. When I go back with the browser back button it does not reload the page and all is fine. The link it produces looks fine to me href="/" In other parts of the app for example going back to the index from /new the same {{link-to}} helper works fine.
