มีใครใช้ autocomplete bootstrap ขอแนะนำหน่อยครับ

<script>
$(function(){
  var brand = [
  <?php
  $ResultBrand = $Class->selectField("SELECT * FROM brand");
  foreach($ResultBrand as $Brand):
  ?>
    { value: '<?=$Brand['name']?>', data: '<?=$Brand['id']?>' },
  <?php endforeach?>
  ];
  
  // setup autocomplete function pulling from currencies[] array
  $('#brand').autocomplete({
    lookup: brand,
    onSelect: function (suggestion) {
      var thehtml = '<strong>Currency Name:</strong> ' + suggestion.value + ' <br> <strong>Symbol:</strong> ' + suggestion.data;
      $('#outputcontent').html(thehtml);
    }
  });

function JsonData(){
		$connnectPO=conDB::Con_DB();
		$sql = "SELECT 
			a.answer_running AS answer_running,
			a.answer_code AS answer_code,
			a.answer_name AS answer_name,
			vc.emp_fullname AS create_by,
			DATE_FORMAT(a.create_date,'%d/%m/%Y %H:%i:%s') AS create_date,

		$sql .= " LEFT JOIN hr_system.vw_emp_name vc ON a.create_by = vc.emp_code2";
		$sql .= " LEFT JOIN hr_system.vw_emp_name vu ON a.update_by = vu.emp_code2";
		$sql .= " WHERE a.company_code='$_SESSION[company_code]'";
		$sql .= " order by a.answer_running ASC";
		$charset = $connnectPO->query("SET NAMES UTF8");
		$result = $connnectPO->query($sql);
		if ($result){
			$num = $result->num_rows;
			if ($num > 0) {
			$dataArray = array();
    		while($row = $result->fetch_assoc()){
             	 $data = $row;
                array_push($dataArray,$data);
         	}
				echo "{\"total\":$num,\"data\":".json_encode($dataArray)."}";				
			}else{
