How to send checkboxes values from HTML to Node JS?

I tried to send some checkboxes values from HTML to Node JS. In my HTML file, I have some checkboxes in a table. I got the checked checkboxes values as following,

$("#createSS").click(function (event) {
    event.preventDefault();
    var searchIDs = $("#imgTable input:checkbox:checked").map(function () {
        return $(this).val();
    }).get();
    console.log("selected::::" + searchIDs);
});

My HTML form is,

<form action="/addSlideShow" method="POST">
    <table id="imgTable" class="table">
        {{#images}}
            <tr>
                <td><input id={{imgURL}} type="checkbox" name="ch" value={{imgURL}}/></td>
            </tr>
        {{/images}}
    </table>

    <input id="createSS" type="submit" value="Create Slide Show" class="btn btn-success pull-left" disabled/>&nbsp;&nbsp;

</form>

In Node JS,

app.post('/addSlideShow', function (req, res) {
    var $ = req.body;
    $('td').each(function () {
        console.log($(this).text());
    });
});

When I'm clicking the button in HTML, the for isn't submit. How may I fix this?

Thanks in Advance!
