title: Reload ajax magnific pop-up
body: <p>I have a magnific pop-up like </p>
  
  <pre><code>$.magnificPopup.open({
              items: {},
              type: 'ajax',
              ajax: {
                  settings: {
                      url: some_url,
                      dataType: 'json',
                      method: 'POST',
                      data: params
                  }
              },
              key: 'basket_popup'})
  </code></pre>
  
  <p>first time it works fine. But assume, I have <code>params</code> like <code>{'zz':'mm'}</code>.
  If I call this function second time and pass new params, I see that in network magnific sends old request. How to avoid it (except calling <code>magnificPopup.close()</code>)?</p>
