Checkbook value automatically sending on submit button

I am trying to pass a checkbox value of modal form using AJAX but without checking the check-box. Whenever I click on the submit button it automatically selects the checkbox and sends its value. Why is all that happening?

<div class="checkbox">
    <label>
        <input type="checkbox" name="remember" id="remember" <?php if(isset($_COOKIE['username'])) { ?> checked <?php } ?>>
        Remember me
    </label>
</div>

$('#login_Modal').click(function(e) {
    e.preventDefault();
    var username = $('#loginUsername').val();
    var password = $('#loginPassword').val();
    var remember = $('input[name="remember"]').prop('checked'); 

    if ($("#loginUsername").val() === '') {
        $("#loginUsername").parent().addClass('has-error');
        $("#loginUsername").focus();
        //errCount++;
    } else if($("#loginPassword").val() === '') {
        $("#loginPassword").parent().addClass('has-error');
        $("#loginPassword").focus();
    } else {
        $("#loginUsername").parent().removeClass('has-error').addClass('has-success');
        $.ajax({
            url: "form_login_process.php",
            type: 'POST',
            data: {
                'Username': username,
                'Password': password,
                'Remember' : remember
            },
            success: function(data) { 
                alert(data);
            }

The AJAX response shows "on".
