title: add delay on onChange event in ionRangeSlider
body: <p>I am using a ionRangeSlider for price range:</p>
  
  <p>HTML</p>
  
  <pre><code>&lt;input class="range-slider" id="price_range"&gt;
  </code></pre>
  
  <p>JS</p>
  
  <pre><code>        $("#price_range").ionRangeSlider({
              min: 0,
              max: 10000,
              type: "double",
              grid: false,
              step: 500,
              force_edges: true,
              decorate_both: false,
              prettify_enabled: true,
              onChange: function (data) {
                  $('#loading').show();
                  window.location.replace("@Url");
              },
          });
  </code></pre>
  
  <p>I want to add a delay of 2 seconds on <code>onChange</code> before redirecting to the url.</p>
  
  <p>I have looked into the documentation but I can't find how to add a delay to the  <code>onChange</code> event. </p>
  
  <p>Any help would be appreciated</p>
