Change div content dynamically on ng-click AngularJS
<p>I want to display some data and tables in the content <code>div</code> which depends on which category you choose on the left hand side navigation.
So if I change the category also the displayed content of the content div should change.</p>

<p>Here is my code on <a href="https://plnkr.co/edit/knaGTyenFzUnggQ3UYWG" rel="nofollow">Plunkr</a>.</p>

<p>But it seems that not even this simple example is working.</p>

<p>So I have two Questions:</p>

<p>1.) How can I fix this example code to run ?</p>

<p>But more important:</p>

<p>2.) <strong>Is there a better way to change the content div when you change the category ?</strong></p>
