clojurescript closure problem
; This fails:
(doseq [hid ["a" "b" "c"]]
(goog.dom.appendChild (goog.dom.$ "some-element-id") (goog.dom.createDom "div" (.strobj {"id" hid}) (str "Test-"hid)))
(goog.events.listen (goog.dom.$ hid) goog.events.EventType.CLICK, (fn [e] (js/alert hid))))
;This works:
(defn hidfn [hid]
(fn [e] (js/alert hid))
)
(doseq [hid ["a" "b" "c"]]
