Autocomplete Response function normalizes data?

Autocomplete Response function normalizes data?

I have a stackoverflow question here regarding how response works and why its printing my HTML tags in the final output.

  1.     $('#mainSearch').autocomplete({
  2.         appendTo: ".inputWrapper",
  3.         minLength: 3,
  4.         source: function (request, response) {
  5.             var customer = new Array();
  6.             $.ajax({
  7.                 async: false,
  8.                 cache: false,
  9.                 type: "POST",
  10.                 url: "http://localhost/EmployeeDirectory/GetEmployees",
  11.                 data: { "filterText": request.term },
  12.                 error: function (data) { console.log('Error!'); },
  13.                 success: function (data) {
  14.                     for (var i = 0; i < data.length ; i++) {
  15.                         customer[i] = {
  16.                             label: data[i].FullName + "<a href='#'>" + data[i].Region + '/' + data[i].District + "</a>" + data[i].Center,
  17.                             Id: data[i].UserID,
  18.                             encryptID: data[i].UserIDEncryted
  19.                         };
  20.                     }
  21.                 }

  22.             });
  23.             response(customer);
  24.         }
  25.     });

How can I get my response to allow for the HTML tags within the outputted <li>'s ?
