fail function called even after ajax post

fail function is being called even after the ajax post has been made followed by always function being called but done function is not called. Why it's happening ?

$('#askques').submit(function(event) {  
            event.preventDefault();               
            $.ajax({
                        type: 'POST',
                        url: 'post.php',
                        data: $(this).serialize(),
                        dataType: 'json',
                       })
                       .done(function(data) { alert( data );})
                       .fail(function() {alert( "error" ) ;})
                       .always(function(data) 
                       {alert(data);
                        $(".sub").attr("disabled","1"); 
                      });
                    });

Post.php

<?php

//error_reporting(0);

//$data = json_decode(file_get_contents("php://input"));

$fname = $_POST["fname"]; //$data->name;
$lname = $_POST["lname"];//$data->fname;
$ques = $_POST["ques"];//$data->ques;
$ans = $_POST["ans"];//$data->ans;

$myfile = fopen("data.txt", "w") or die("Unable to open file!");

$txt = $fname." ".$lfname." ".$ques." ".$ans;

fwrite($myfile, $txt);

fclose($myfile);

//$data = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);
//echo json_encode($data);

echo "Done";

?>

The dataType: 'json', designates that the return type from server must be a valid JSON, yet your server is not sending JSON back. Either remove the dataType from request, or encode your response as JSON
