Introducing Om
The Om library (https://github.com/omcljs/om) is a great tool for building dynamic user interfaces in ClojureScript. In fact, it's an interface to React.js (http://facebook.github.io/react/), which is a JavaScript library for creating interactive user interface components.

In this way, Om components react to changes in their state.
Note
The following library dependencies are required for the upcoming examples:
[org.omcljs/om "0.8.8"]
Also, the following namespaces must be included in your namespace declaration:
(ns my-namespace (:require [om.core :as om :include-macros true] ...
