没有从使用jquery、Ajax的选择框上的提交按钮获得任何输出

你好，我有选择框，我想从过去4,6周选择新闻，并根据提交按钮相应地显示新闻。我使用以下代码来创建jquery,ajax和尝试传递值到php。但是我不知道当我从选择框中选择并点击提交按钮时，什么都不会显示。我想我正在做一些严重的错误，无法与php和jquery,ajax正确通信。这是Jsfiddle demo。谢谢下面是我的代码:

dashboard.php

if($param['aktion'] == 'get-widget-news-edit')
{
    if(isset($_POST['saveId']))
   {
      if(($_POST['news'])==4){
      echo "You have selected news for last 4 weeks";
}
 if(($_POST['news'])==6){
     echo "You have selected news for last 6 weeks";
}
}
    $html = '<table width="538" cellspacing="0" cellpadding="0" border="0" >
            <tr>
                <td>
                <div>'.CreateRegister($page['register-news']).'</div>
                '.CreateMessage().'
                <div class="cont-liste-verlauf register">
                    <div class="tab-content">
                        <div id="tab1" class="tab" style="display:block">
                            <table id="news">
                            <form name="UserInformationForm" method="POST" >
                        <select name="news">
                                <option value="4" '. (($_POST['news']=="4")  ?  "selected=selected" : "" ) .'>Show news from last 4 weeks</option>
                                <option value="6" '. (($_POST['news']=="6") ?  "selected=selected" : "") .'>Show news from last 6 weeks</option>
                        </select>
                        <br/><br/>
                    <input type="Submit" name="saveId" id="saveId">
                            </form> 
                            </table>
                        </div>
                    </div>
            </td>
        </tr>
    </table>';
    $return = array(
    'status' => 1,
    'html'  => $html
);
echo json_encode($return);
die();

}

dashboard.js

function getNewsWidgetEdit()
    {
        $.ajax({
        type: "POST",
        url: "ajax/dashboard.php",
        dataType : 'json',
        cache: false,
        data: {'aktion' : 'get-widget-news-edit'},
        success: function(data){
            $('#news').html(data.html);
        }
      });
  }

            $('#news .butt-rahmen').live('click', function(){
            if($(this).attr('id') == 'saveId')
                getNewsWidgetEdit();

    });
