p>When you want fresh objects to be created for every lookup,
register your factories as non-singletons using the <code>singleton: false</code> option.</p>

<div class="filename javascript"><div class="ribbon"></div><span>app/initializers/notification.js</span><pre class="language-javascript line-numbers"><code class="javascript language-javascript"><span class="token keyword">import</span> EmberObject <span cla
