Week day and moment js
<p>I have this code:</p>

<pre><code>var day = $("#date-filter").val();
</code></pre>

<p>The value of this input is: "22/03/2016".</p>

<p>I need week day.</p>

<p>I tried to do it in 2 ways but it does not work.</p>

<p>1) <code>moment(day).day()</code></p>

<p>2) <code>moment($("#date-filter").val()).day()</code></p>
