can anyone help in re-learn library for reagent

https://github.com/oliyh/re-learn/blob/master/example/checkout/checkout/app.cljs - here is an example

(def re-learn-component
  (re-learn/with-lesson
    {:id :basic-lesson
     :description "Just testing how to use re-learn"
     :position :bottom}
    (fn []
      [:div
       [:div.h3
        [:h3 "Ich bin Dhiren Serai"]]])))

(def check-re-learn
  (re-learn/with-tutorial
    {:id :test-tutorial
     :name "check list"
     :description "create your learning components"
     :lessons [{:id :willkommen
                :description [:div
                              [:h2 "Welcome"]]}
               re-learn-component]}
    (fn []
      [:div
       [:h5 "Hallo"]
       [re-learn-component]])))

(defn mount-root
  ;;;Start of the application
  []
  (re-learn/init)
  (r/render [check-re-learn] (by-id "test")))

(.addEventListener js/document "deviceready"
                   mount-root
                   false)

its just rendering the headers but re-learn components are not working
