New validation with jQuery doesn't send tha value

I want to make double verification to Emails, first verify is email is accepted ( is not an incorrect mail like gimil.com homail.com ... etc)

and second verification to know if email is existed,

I try to do with this code jQuery

$('#signup').validate(
errorElement: 'span',
rules:
Email:
required: true,
email: true,
remote:
url: '/verifiyEmail',
type: 'POST', //Or whatever
data: function()
return $("#email").val(); // The value of the email field
,
dataType: "JSON",
dataFilter: function(responseData)
alert(responseData.message); // Or whatever
return responseData.isValid; // validation result




);


and the PHP code

if(isset($_POST['email']))
$email = $_POST['email'];
$response = null;
$isInBlackList = Member::Accepted($email);
if($isBlackList)
// User is in the blacklist
$response = array("isValid"=>false, "message"=>"This email is blacklisted!"); // Initialize $response

else
$alreadyExists = ! Member::($email); // You have to implement this.
if(!$alreadyExists)
// Email already exists
$response = array("isValid"=>false, "message"=>"This email is already in user"); // Initialize $response

else
// We found a valid email
$response = array("isValid"=>true);


header('Content-Type: application/json');
echo json_encode($response);
else
$response = array("isValid"=>'error');
header('Content-Type: application/json');
echo json_encode($response);



And always the response is error, that mean the Email is doesn't send to PHP code

error

is there any solution?

data: email: $("#email").val()

console.log(responseData);

console.log
