Google recaptcha Implementation in Site Studio Custom Forms

Question

I am implementing recaptcha in my custom html forms which i have defined in custom component resource.for recaptcha implementation i am using recaptcha4j-0.0.7.jar ,on form submit it calls my custom service 'MyMail' which executes javafunction where i am calling recaptcha fuction to verify recaptcha text and after that sending Form details to given Email Address.*But when i am redirecting to same page for sending message for recaptcha response all form fields values goes blank.*
Is there any other way to retain form values when my service returns recaptcha response?
<form id="DataForm10" class="form" action="<$HttpCgiPath$>?IdcService=My_MAIL" method="post">
<fieldset class="rc_grey">
<input type="hidden" name="Email" value="<$email$>"/>
<input type="hidden" name="RedirectUrl" value="<$ssGetServerRelativeUrl(siteId, nodeId)$>"/>
<ol>
<li>
<div class="grid_4 alpha">
<label for="name"><em> *</em>Your Name</label>
</div>
<div class="grid_5">
     <input type="text" name="name" id="name" class="mandatory"/>
</div>
</li>
<li>
<div class="grid_4 alpha">
<label for="reference_no"><em> *</em>Your Reference No (located top left of payslip)</label>
</div>
<div class="grid_5">

Hi Mikey,
This code is not working because when i am redirecting on same Form page all m_binder data will lost , so the response data will be blank on page after redirecting.You can see theprevious form code where i have specified RedirectUrl input hidden field and in my java fucntion i am only appending Response message with RedirectUrl parameter.
if (reCaptchaResponse.isValid()) { 
          // this command is used to send email to the client. The message
               // sent is a template (Mail), and the data to format the
               // message is taken out of m_binder, contained in "this"
          boolean response=InternetFunctions.sendMailTo(emailStr, "Mail", subject, this.m_service);
               redirecturl=redirecturl+"?Response="+response;
               m_binder.putLocal("RedirectUrl",redirecturl);
     } else {
          redirecturl=redirecturl+"?valid="+reCaptchaResponse.isValid();
               m_binder.putLocal("RedirectUrl",redirecturl);
          }catch(Exception e){
               e.printStackTrace();
               redirecturl=redirecturl+"?error="+e.getMessage();
               m_binder.putLocal("RedirectUrl",redirecturl);
so please tell me is there any other way to submit my custom form and will display previous form field values entered by user when recaptcha response will  show on same page  through my service.
Thanks
