you need pass event function string. dom handle it

$(document).ready(function () {         $.ajax({             url: '/api/userapi/',             type: 'get',             contenttype: "application/json;charset=utf-8",             datatype: "json",             success: function (data) {                  alert('user added successfudly');                  (var = 0; < data.length; i++) {                          $("#absa").append("<tr><td>" + data[i].user_name + "</td><td>" + data[i].address + "</td><td>" + data[i].email + "</td><td>" + data[i].mobileno + "</td><td><button onclick='update()'/></td></tr>");                 }             },             error: function () { alert('user not added'); }         });      });
