Bootstrap checkbox not showing on table

<tbody class="body">
                    <tr>
                        <td><input type="hidden" class="form-control" name="count[]" value="1"><span>1</span</td>
                        <td><input type="text" class="form-control" name="item[]" placeholder="item"/></td>
                        <td><input type="text" class="form-control" name="description[]" placeholder="description"/></td>
                        <td><input type="text" class="form-control quantity" name="quantity[]" placeholder="quantity"/></td>
                        <td><input type="text" class="form-control price" name="price[]" placeholder="price"/></td>
                        <td><input type="text" class="form-control item_discount" name="item_discount[]" value="0" placeholder="item discount"/></td>
                        <td><input type="text" class="form-control total" name="total[]" placeholder="total" readonly=""/></td>
                        <td><input type="checkbox"></td>
                    </tr>
                </tbody>
            </table>
        </div>

The code above displays everything but the checkbox.

Any advice would be grateful. thanks
