Magento 1.9 Mage, execute javascript command when customer successfully registers

Question

I'm trying to execute a java-script command when the customer successfully registers an account, I tried the following, but the java-script command doesn't get executed.

Does somebody now how I can achieve this? Thank you in advance.

[EDIT] I actually fixed it myself, I wanted to send some customer data to the html page via javascript. If you want to achieve this, please read my answer.

After some more digging, and thanks to the answers from kiatng and lalit mohan, I found the answer.

I wanted to list all customer details to the page via javascript.

In the mage.php file, located at Magento\apps\magento\htdocs\app:

 public static function dispatchEvent($name, array $data = array())
{
    //Custom code, this is being executed when the customer succesfully registers
    if($name == "customer_register_success")
    {
        $customer = $data['customer'];
        $customerData = Mage::getModel('customer/customer')->load($customer->getId())->getData();

        $out = "";
        foreach( $customerData as $key => $value ) {
            //this prevents the password hash to be show in the session  
            if(!$key == "password_hash")
            {
                $out .= "|" . $key . ':' . $value;
            }
        }

        //Put customer vallues in the sessions
        session_start();
        $_SESSION["data"] = $out;
    }

  //Logging to htdocs/var/log/system.log
  Mage::log('Event fired:  ' . $name . "__" . $data);

  //Default code (this was already there)
  Varien_Profiler::start('DISPATCH EVENT:'.$name);
  $result = self::app()->dispatchEvent($name, $data);
  Varien_Profiler::stop('DISPATCH EVENT:'.$name);
  return $result;

}

Then in your javascript:

var customerdata = "<?php session_start(); echo $_SESSION["data"]; ?>";

This will output all customer data to a string.

you can run profiler to debug problem by edit temporarily Mage.php file. so you can output of all events for particular request..
File: app/Mage.php

public static function dispatchEvent($name, array $data = array())
{
    Mage::log('Event: ' . $name); //not using Mage::log, as 
    //file_put_contents('/tmp/test.log','Dispatching '. $name. "\n",FILE_APPEND); //poor man's log
    Varien_Profiler::start('DISPATCH EVENT:'.$name);
    $result = self::app()->dispatchEvent($name, $data);
    #$result = self::registry('events')->dispatch($name, $data);
    Varien_Profiler::stop('DISPATCH EVENT:'.$name);
    return $result;
}

In order to execute your js, you'll need to find a way to always redirect to the page where you have your js embedded. You can do this by hard-setting the success_url. One way to do this is to listen to the event customer_success_event, as indicated in your attached image. After you have set this up, then the code is quite simple:

public funstion setCustomerRegisterSuccessUrl($observer)
{
    $successUrl = Mage::getUrl('your_module/your_controller/your_action');
    $controller = $observer->getEvent()->getAccountController();
    $controller->getRequest()->setParam('success_url', $successUrl);
}
