Magento 1.9 – controller_action_predispatch Event Not Firing Observer

This is the first observer I'm writing. I'm testing the observer with the controller_action_predispatch that should fire when I load a page as an example. This is the files I created:

/app/etc/modules/EPS_CustomizationURL.xml

<?xml version="1.0"?>
<config>
    <modules>
        <EPS_CustomizationURL>
            <codePool>local</codePool>
            <active>true</active>
        </EPS_CustomizationURL>
    </modules>
</config>

/app/code/local/EPS/CustomizationURL/etc/config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <EPS_CustomizationURL>
            <version>0.0.1</version>
        </EPS_CustomizationURL>
    </modules>
    <global>
        <models>
            <epscustomizationurl>
                <class>EPS_CustomizationURL_Model</class>
            </epscustomizationurl>
        </models>
    </global>
    <adminhtml>
        <events>
            <!-- observe the event -->
            <controller_action_predispatch>
                <observers>
                    <epscustomizationurl>
                        <class>epscustomizationurl/observer</class>
                        <method>epsURLCreator</method>
                    </epscustomizationurl>
                </observers>
            </controller_action_predispatch>
        </events>
    </adminhtml>
</config>

/app/code/local/EPS/CustomizationURL/Model/Observer.php

<?php 
class EPS_CustomizationURL_Model_Observer {
    public function epsURLCreator($observer) {
        $this->_redirectUrl("http://www.google.com");
    } 
}
?>

So, as far as I understand as soon as my page loads or even before it I should be redirected to http://www.google.com. This is the only way I could think of to know if my observer is firing.

What am I missing? Any wrong naming, wrong event or _redirectUrl is not working? I'm on Magento 1.9.

EDIT:
All the caches are disabled so the cache should not be the problem:

I also tried just logging something instead of redirect and changing the event to customer_login:

<?xml version="1.0"?>
<config>
    <modules>
        <EPS_CustomizationURL>
            <version>0.0.1</version>
        </EPS_CustomizationURL>
    </modules>
    <global>
        <models>
            <epscustomizationurl>
                <class>EPS_CustomizationURL_Model</class>
            </epscustomizationurl>
        </models>
        <events>
            <!-- observe the event -->
            <customer_login>
                <observers>
                    <eps_customizationurl_model_observer>
                        <type>model</type>
                        <class>epscustomizationurl/observer</class>
                        <method>epsURLCreator</method>
                    </eps_customizationurl_model_observer>
                </observers>
            </customer_login>
        </events>
    </global>
</config>

And my observer:

<?php 
class EPS_CustomizationURL_Model_Observer {
    public function epsURLCreator($observer) {
        Mage::log('I just made an Observer!', null, 'system.log', true);
    } 
}

But still can't see anything in /var/log/system.log
