I have used a spinner like this code below:

Try the code below to get the value when you click button up or down of spinner and show that value on message box.

<script type="text/javascript">
 $.subscribe("changeTopic", function(event,data) {
     alert($("#spinner2").val());
 });
</script>
<sj:spinner
    label="Select a Number"
          name="spinner2"
          id="spinner2"
          onChangeTopics="changeTopic"
          min="5"
          max="50"
          step="2"
          value="25"/>
