api.controller=function($scope) {
  /* widget controller */
  var c = this;
	$scope.userUpdate=function(user){
		$scope.data.name=user.name;
		$scope.data.email=user.email;

(function() {
  /* populate the 'data' object */
  /* e.g., data.table = $sp.getValue('table'); */

      /*1. Declare the array*/
	data.array=[];
/*2. Glide record on table*/
var grInc = new GlideRecord('u_artificatory');
grInc.Query('sys_id','122');
grInc.query();

while(grInc.next()){
/*2.1 Create empty object*/
data.array.push({
               /*2.2 Set object values*/
name:grInc.u_name.toString(),
email:grInc.u_class.toString(), 
mobile:grInc.u_section.toString()
