update template destroys event handlers

[avescodes]

io.pedestal.app.render.push.templates/update-template uses dom/set-html! to re-render its data. This is a problem if you have previously placed event listeners on the html element that was previously there, it gets wiped out.

[domina :as dom]
[domina.css :as dc]
[domina.events :as de]

(de/listen! (dc/sel "h1") :dblclick 
     (fn [e] (dom/set-html! (dc/sel "#stuff") "I am new html")))
(de/listen! (dom/by-id "stuff") :dblclick 
      (fn [e] (.log js/console "I was clicked on")))

<h1>Header</h1>
<div id="stuff">Click on me</div>

You can use the event handler for #stuff until you double click the header, then it will wipe out #stuff. It no longer responds to double click events.
