I call a js function using component-did-mount\: 

(def load-map (with-meta identity
                {:component-did-mount
                 loadMap}))

(defn map []
    [load-map [:div {:id "this-div"} "hello"]]
)
But only want to call loadMap once per page load. :on-mount doesn't work loadMap can't be called directly on the page load in an effects handler  because this-div needs to be mounted before loadMap is called because loadMap accesses the div using the this-div id
