How can I get the the value of the hidden field with the class "OriginalSuggestedQty" when a checkbox within the row is checked?

Here is what the HTML looks like:

```
<input class="OriginalSuggestedQty" type="hidden" value="5">
<tr>
    <td >
        <input class="SuggestedQty" id="items_1__SuggestedQty" type="text" value="9">
        <input checked="checked" class="suggested"type="checkbox" value="true">
    </td>
</tr>

```

This is what i currently have:

```
$(".suggested").change(function() {
    if ($(this).is(":checked")) {
        var originalVal = $(this).closest('.OriginalSuggestedQty').val();
        $(this).closest('tr').find('.SuggestedQty').val(originalVal);
    }
});

```
