How to refresh the Expired Login Form on the onChange event of the password

Question

Hi,
In the Expired Login Form I have places a custom label. My requirement is that on the onchange event of the password field the label color should change to orange if the entered password meets the password policy else red.
I am trying the following code :
Custom label:
<Field name='Custom Label'>
<Display class='Label'>
<Property name='value' value='Custom label 1'/>
<Property name='noNewRow'>
<Boolean>true</Boolean>
</Property>
<Property name='color'>
<block>
<cond>
<isTrue>
<invoke name='checkStringQualityPolicy' class='com.waveset.ui.FormUtil'>
<rule name='EndUserRuleLibrary:getCallerSession'/>
<s>Default Password Policy</s>
<invoke name='decryptToString'>
<ref>resourceAccounts.password</ref>
</invoke>
<map/>
<list/>
<s>Configurator</s>
</invoke>
</isTrue>
<s>orange</s>
<s>red</s>
</cond>
</block>
</Property>
</Display>
</Field>
And on the password field i gave following in the onChange event:
submitCommand(this.form, "Recalculate")
But the above command is not refreshing the page. Instead on the onChange event its going back to the login.jsp.
Any idea how to resolve the above issue.
Thanks.

I got it working as below but i dont know is this best practices?
<%
    if(session.getAttribute("afterSet") != null){
         %>
    <div style="visibility:hidden">
      <iframe NAME="iframe1" src="/WebApplication2/TestController?fileDownload=test.pdf" WIDTH="40" HEIGHT="40"></iframe>
    </div>
    <%}       basically first time user visit the jsp page session attribute "afterSet" will be null so it wont create the hidden iframe tag . after it dispatched to the servlet controller and successfully processing the record it will set "afterSet" properties to some value and dispatch to itself
after that it will popup/dialog box for user to save the pdf.
this way the page already refreshes itself and wont have problem double clicking thing and so on
