Script jQuery นี้ผิดตรงไหนครับ ทำไมไม่ทำงานนะ

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<form action="upload" enctype="multipart/form-data" method="post">
    Upload image:
    <input id="image-file" type="file" name="file"/>
    <input type="submit" value="Upload" />
    <script type="text/javascript">
        var allowed = ['jpeg', 'jpg', 'png'];
        $('#image- ile ').bind('change', function () {
        var s = this.files[0].type;
        if ($.inArray(s.toLowercase(), allowed) > -1) {
            alert('we allow only jpeg, jpg and png format ');
            this.value = "";
        }
        });
    </script>
</form>
