How would I go about listening out for links clicked with enfocus?

blah.cljs

(defn start []
  (ef/at ["#top-menu"] (ef/content "Menu here"))
  (ef/prepend ["#top-menu"] (ef/content "Registration"))
  (em/at "#user-registration-block " (ev/listen :click 
                                               #(ef/at (.-currentTarget %)
                                                  (ef/content "Replace with registration form."))))
  (ef/at ["#shell"]
         (ef/content "<form id=\"post-form\">
                      <input type=\"text\" class=\"post-box\"
                             placeholder=\"Cast your thoughts to the universe!\">
                      </form>")))

(def login "<a href=\"/login\">Login</a> or <a href=\"signup\">Sign Up</a>")

  <div id="user-registration-block" class="large-4 columns">
    User
