How to disable button in ie 10

<li><html:link href="#"
submit="./reviewStatus/removeCaseRangeAssignment"
formName="sampleCaseRangeForm"
disabled="${( (requestScope.actionBean.approvalStatusCode ne null) &&
requestScope.actionBean.approvalStatusCode ne 'UNL') ||
(requestScope.actionBean.reviewStatusDTOCount <= 0)}"
tabindex="${requestScope.tabIndex}">
<span>Remove</span>
</html:link></li>

this code will disable the button in ie 8  but will not disable the button in ie 10

How could I re-code it to work in ie 10

Thank you,

Andy
