title: UIkit Modal Alert JS
body: <p>I use the version of UIkit 3.1.6, in JS I call the UIkit.modal.alert function, but I would like to be able to set some parameters in the modal window, I would like it in the center and with the bg-close and esc-close function set on false.
  With the Uikit 2 version it worked now no, can you help me understand where I'm wrong?</p>
  
  <pre><code>UIkit.modal.alert("test", {bg-close: false, esc-close: false}).then(function () {
     window.location = '/test';
  });
  </code></pre>
