remote button always expects its target defined before and outsite the form in IE

ideal scenario:

<div id="t1">Div 1</div>

<s:form id="form" action="AjaxTest">
<input type=textbox name="data">
<s:submit type="button" theme="ajax" label="Update Content" targets="t1" id="ajaxbtn"/>
</s:form>

but

<div id="t4">
<s:form id="form" action="AjaxTest">
<input type=textbox name="data">
<s:submit type="button" theme="ajax" label="Not posting form content" targets="t4" id="notworking"/>
</s:form>
</div>

doesn't work in IE. Meaning the form values are not posted to the action. While in FF it works like a charm. This is a show stopper for us. Please advise as early as possible..............

you can try with showcase/ajax/remotebutton/index.jsp ... just add the above code-segment.
