Alpaca form submission, stay on same page

I am building a form with PHP and ALPCA (jquery,ajax). I am having trouble with file submitting and staying on the same page. I have tried the recommended techniques for doing as such with AJAX event.preventDefault();, also using hidden frambut with no success. My question is does the ALPACA package require a different method?

FORM SECTION

    <script type="text/javascript">
        $(document).ready(function() {
           $("#form").alpaca({
            "schema": {
                    "title":"User Feedback",
                    "description":"What do you think about this Speaker?",
                    "type":"object",
                    "properties": {
                        "email": {
                            "type":"string",
                            "title":"Email",
                            "required":false
                        },
                        "feedback": {
                            "type":"string",
                            "title":"Feedback"
                        },
                        "ranking": {
                            "type":"string",
                            "title":"Ranking",
                            "enum":['It is Great', 'Not so cool', 'Very poor quality', 'I think there may be a Privacy or Copyright issue'],
                            "required":false
                        }
                    }
                },
                "options": {
                    "form":{
                        "attributes":{
                            "action":"FORM.php",
                            "method":"post"
                            "target":"hiddenFrame"
                        },
                        "buttons":{
                            "submit":{}
                        }
                    },
                    "helper": "What do you think about this Speaker?",
                    "fields": {
                        "email": {
                            "size": 20,
                            "placeholder": "email not nessasary"
                        },
                        "feedback" : {
                            "type": "textarea",
                            "name": "your_feedback",
                            "rows": 4,
                            "cols": 40,
                            "helper": ""
                        },
                        "ranking": {
                            "type": "select",
                            "helper": "",

                        }
                    }
                },
                e.preventDefault();
            });
        });
    </script>

PHP FILE

<?php

$file = "people.txt";
$feedback = $_REQUEST['feedback'];
$ranking = $_REQUEST['ranking'];
$email= $_REQUEST['email'];
$string = file_get_contents("/tmp/live-info");

$json = str_replace('***(', $callback, $string);
$json = rtrim($json, ')');

$json_a = json_decode($json, true);

$current_name = $json_a['current'][name];

$current_name .= "|$email|$ranking";

$feedback .= "|$current_name" .PHP_EOL;

file_put_contents($file, $feedback, FILE_APPEND | LOCK_EX);

?>
