title: trigger alert after jquery isotope filter completes
body: <p>I have jquery isotope setup and have created some filters. When i create I select a filter, isotope does a nice little animation. I want to trigger an alert at the end of the animation.</p>

  <p>Any ideas?</p>
  
  <p>Here is the code for the on click of a filter:</p>
  
  <pre><code>$('.filter').on( 'click', 'a', function( event ) {
          event.preventDefault();
          var $this = $(this);
          // don't proceed if already selected
          if ( $this.hasClass('selected') ) {
              return false;
          }
  
          // console.log('hello world');
          var $optionSet = $this.parents('.option-set');
          var group = $optionSet.attr('data-filter-group');
          options.comboFilters[ group ] = $this.attr('data-filter-value');
          $.bbq.pushState( options );
  
          // COUNT
          var $filtered = $('#isotope-container').data('isotope').$filteredAtoms;
          // get count of all filtered item
          alert($filtered.length);
          // get count of all filtered items that match a selector
          //$filtered.filter('.blue').length;
    });
  </code></pre>
