LeafletJS Hello World in Om and ClojureScript

leaflet-helloworld.cljs

(ns leaflet-helloworld
  (:require [om.core :as om :include-macros true]
            [om.dom :as dom :include-macros true]))

(defn map-view [_ owner]
  (reify
    om/IRender
    (render [_]
      (dom/div #js {:id "the-map"} nil))
    om/IDidMount
    (did-mount [_]
      (let [osm-url "http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png"
            osm-attrib "Map data © OpenStreetMap contributors"]
        (doto (js/L.Map. "the-map")
          (.setView (js/L.LatLng. 0 0) 1)
          (.addLayer (js/L.TileLayer. osm-url 
                                      #js {:minZoom 1, :maxZoom 19, 
                                           :attribution osm-attrib})))))))

I have been looking at this to get leafletJS to work, I added the component and bound it to the om/root... however, besides creating the the-map node it doesn't do anything for me.... perhaps you can post the full source for the example?
