jQuery Isotope `arrangeComplete` listener does not fire
<p>I have the following jQuery code using Isotope plugin:</p>

<pre><code>$(document).ready(function() {

    /**
     * Initialise Isotope
     */
    var $grid = $('.grid').isotope({
        "itemSelector": ".grid-item",
        layoutMode: 'masonry',
        "masonry": {
            "columnWidth": 0
        }
    });

    /**
     * Trigger when arrangement completes
     */
    $grid.on( 'arrangeComplete', function( event, filteredItems ) {
        alert("HERE!");
    });

});
</code></pre>

<p>The alert does not trigger at all although the Isotope grid works. What have I missed? Thanks!</p>
