Django Ajax not entrering in the function

When i press the link the program should go to the ajax function to update the database without reloading the page. the problem is when the link is pressed doesnt enter in the JS function (doesnt show the alert)

 <a href="#" onclick="xpto2()" >Remind later</a>
<script>    
function xpto2(){
     alert("hello");
     $.ajax({
        url: 'update-notify-status-noshow',
        data: { postdata1: {{ n.id }} }, 
        dataType: 'html', 
        type: 'get', )
        success: function(output) {
        alert(output); 
        }
    });
   </script>
