title: Bind multiple times jStepper to input element
body: <p>I use jStepper plugin to my numeric input values. I need to change range of valid digits depend on what value of select input is chosed. I have sample demo on <a href="http://jsfiddle.net/vqjb2/1/" rel="nofollow">http://jsfiddle.net/vqjb2/1/</a>.</p>
  
  <pre><code>&lt;input type="text" id="testId" /&gt;
  
  &lt;select id="select"&gt;
    &lt;option value="1"&gt;1&lt;/option&gt;
    &lt;option value="2"&gt;2&lt;/option&gt;
  
  &lt;/select&gt;
  
  $("#testId").jStepper({ minValue: 0, maxValue: 20, minLength: 1, defaultValue: 0 });
  
  $("#select").on("change", function(event) {
  
      var val = $(this).val();
      if(val == 1) {
           $("#testId").jStepper({ minValue: 0, maxValue: 20, minLength: 1, defaultValue: 0 });
      }
      else if (val == 2) {
           $("#testId").jStepper({ minValue: 0, maxValue: 5, minLength: 1, defaultValue: 0 });
      }
  });
  </code></pre>
  
  <p>When page is loaded it works fine because max value is 20. Then when I change value of drop down to "2" max value is 5 and it works fine too, but when I change it to "1" again it still have max value of 5 instead of <code>20</code>.</p>
