Switch divs off/on
<p>Once a div is offed can it be onned?</p>

<p>FIRST,</p>

<pre><code>        $("#num-one").off();
        $("#num-two").off();
        $("#num-three").off();
</code></pre>

<p>THEN LATER ON,</p>

<pre><code>        $("#num-one").on();
        $("#num-two").on();
        $("#num-three").on();
</code></pre>

<p>Because the divs are no longer responding to click events in spite of onning them - can they be onned once they are turned off?</p>
