Не удалось удалить двойные кавычки из строки JSON. ⇐ Jquery

[Anonymous]

Мне не удалось удалить двойные кавычки из строки json. Мой код следующий:
var values = {};
$.each($('#regForm :input'), function(i, field) {
if (field.name == "submit") {
delete field.name;
} else {
values[field.name] = field.value;
}
});
var json_text = JSON.stringify(values);
var global = JSON.parse(json_text);
console.log(global);
$.ajax({
type : "POST",
dataType : "JSON",
data : global,
url : "http://localhost:8080/SpringRestServices/register",
beforeSend : function(xhr) {
xhr.setRequestHeader("Accept", "application/json");
xhr.setRequestHeader("Accept-Encoding", "utf-8");
xhr.setRequestHeader("Content-type", "application/json");
},
success : function(data) {
alert("success"+data);
console.log("Success:", data);
},
error: function(xhr, textStatus, errorThrown) {
console.log("HI");
alert("Failed to cancel subscription! Message:" + textStatus /*+ jqXHR.errorThrown + xhr.responseText*/);
alert("readyState: " + xhr.readyState);
alert("responseText: "+ xhr.responseText);
alert("status: " + xhr.status);
alert("text status: " + textStatus);
alert("error: " + errorThrown);
}
});

Вот мой вывод, когда я вижу его в отладчике Firefox:
"{"username":"hi","email":"hi@gmail.com","password":"123"}"

Мне нужен реальный результат:
{"username":"hi","email":"hi@gmail.com","password":"123"}

Это код моего сервера:
@RequestMapping(value = "/register", method = RequestMethod.POST)
@ResponseBody
public RegisterResponse newAccount(@RequestBody Register registration) {
String newAccountSql = "INSERT INTO register (email,password,username) VALUES (:email,:password,:username)";
RegisterResponse regResponse = new RegisterResponse();
regResponse.setResult(-1);
// ServiceDataBean retBean = new
// ServiceDataBean();
try {
System.out.println("register service calling.....");
MapSqlParameterSource namedParameters = new MapSqlParameterSource();
namedParameters.addValue("email", registration.getEmail());
messageDigest = MessageDigest.getInstance("MD5");
byte[] md5 = new byte[64];
messageDigest.update(
registration.getPassword().getBytes("iso-8859-1"), 0,
registration.getPassword().length());
md5 = messageDigest.digest();
namedParameters.addValue("password", convertedToHex(md5));
namedParameters.addValue("username", registration.getUsername());
GeneratedKeyHolder generatedKeyHolder = new GeneratedKeyHolder();

// TODO what to do with the updInt also check it's not -1
int updInt = jdbcTemplate.update(newAccountSql, namedParameters,
generatedKeyHolder);
regResponse.setResult(0);
System.out.println("from register");
} catch (Throwable e) {
regResponse.setResult(001);
e.printStackTrace();
}
return regResponse;
}
