Replace remove checkbox in shopping cart with button

Hello,

I tried this solution:
1) Copy and paste the "default.cshtml" file to the "Themes/DefaultClean/Views/Shared/components/OrderSummary," folder

2) Open this copied file, and then find following block of code

<td class="remove-from-cart">
                                <span class="td-title">@T("ShoppingCart.Remove"):</span>
                                <input type="checkbox" name="removefromcart" value="@(item.Id)" />
                            </td>

replace with following code

<td class="remove-from-cart">
                                <span class="td-title">@T("ShoppingCart.Remove"):</span>
                                <input type="checkbox" id="[email protected]" name="removefromcart" value="@(item.Id)" />
                                <span data-checkbox-id="[email protected]" class="remove-from-cart-item-action ico ico-delete"></span>
                            </td>

3) And then, add following javascript block at the bottom of this file

<script type="text/javascript">
    $(document).ready(function () {
        var container = '.order-summary-content';
        $('.remove-from-cart span.remove-from-cart-item-action', container).on('click', function () {
            $('#' + $(this).data('checkbox-id'), container).prop('checked', true);
            $('.update-cart-button', container).click();
        });
    });
</script>

4) Finally, add following line of codes to the "styles.css" file (inside the "Themes/DefaultClean/Content" folder)

/* Custom remove icon button for each item in the shopping-cart */
.order-summary-content .remove-from-cart > input[type='checkbox'] {
    display: none;
}
.order-summary-content .ico {
    display: inline-block;
    height: 16px;
    width: 16px;
}
.order-summary-content .remove-from-cart > .ico-delete {
    background: url(images/ico-delete.gif) center center no-repeat;
}

It works for one thing, it does not show me the gif.
I have a gif named ico-delete.gif in my images folder.

I am using 4.0

Please advice?
Thanks,
Rob Nowee
