The submit button should be enabled only when any checkbox is clicked using jQuery

I'm facing the following issue; the submit button should be enabled only when any checkbox is clicked. Using jQuery the code I have is:

$(document).ready(function() {
    var the_terms = $("#pricingTierId");
    the_terms.click(function() {
        if ($(this).is(":checked")) {
            $("#submitBtn").removeAttr("disabled");
        } else {
            $("#submitBtn").attr("disabled", "disabled");
        }
    });
});

<c:if test="${fn:length(incentiveList) gt 0}">
    <input type='button' name="submit" id = "submitBtn" value='Submit Incentives' onClick='execute();' />
</c:if>

However in the checkbox code I have the following

<td>
    <s:checkbox name="checkboxes[%{#stat.index}]" theme="simple" id="%{pricingTierId}"/>    
</td>

my id attribute is defined as id="%{pricingTierId}" so I cannot really pass that in the JQery function as shown above. Please suggest the suitable way
