title: UI spinner bug when changing value using mouse up and down
body: <p>I added the decimal spinner to my site. </p>
  
  <p>My value was 56.20. 
  When I change use mouse wheel up, I am expecting 57.20, but now it is showing 57:00. </p>
  
  <p>The function is shown below: </p>
  
  <pre><code>&lt;script&gt;
    $(function() {
      $( "#spinner" ).spinner({
        step: 1.00,
        numberFormat: "n"
      });
  
      $( "#culture" ).change(function() {
        var current = $( "#spinner" ).spinner( "value" );
        Globalize.culture( $(this).val() );
        $( "#spinner" ).spinner( "value", current );
      });
    });
    &lt;/script&gt;
  </code></pre>
