Unable to validate magento custom login form in fancybox

Question

I am trying to validate the following form in fancybox popup but it keeps on submitting the form instead of doing the validation what am I doing wrong in this? This works perfectly when Outside fancybox.

<form id="login-form-popup" method="post" action="<?php echo $this->getUrl('customer/account/loginPost') ?>">
                 <input name="form_key" type="hidden" value="<?php echo Mage::getSingleton('core/session')->getFormKey() ?>" />
                 <li>
                    <div class="input-box">
                        <label>Email ID</label>
                    <input type="text" placeholder="<?php echo $this->__('Email ID') ?>" class="input-text required-entry validate-email" name="login[username]" id="email" title="Email Address" />
                    </div>
                 </li>
                 <li>
                    <div class="input-box">
                        <label>Password</label>
                    <input type="password" placeholder="<?php echo $this->__('Password') ?>" class="input-text required-entry validate-password" name="login[password]" id="pass" title="Password" />
                    </div>
                </li>
                <li>
                     <div class="input-box">
                    <input class="buttonstyle" type="submit" value="<?php echo $this->__('Login') ?>" name="subloginpop" id="subloginpop" />
                    </div>
                </li>
                <li><div class="input-box">
                     <a class="forgot-password" href="<?php echo $this->getUrl('customer/account/forgotpassword') ?>">Forgot Your Password?</a></div>
                </li>
                </form>
<script  type="text/javascript">
//<![CDATA[ 
 var theLoginFormpop = new VarienForm('login-form-popup', true);
//]]> 
</script>
