Magento Custom Payment Gateway does not launch “authorization” or “capture” methods

So, horray - I'm trying to create a new custom payment gateway. It is intended for authentication / capture through a third-party API, but should NOT be redirected to a third-party site.

From my understanding, when an order is placed / finalized in Magento, and the gateway is set to “Authorize and capture”, it should disable the “capture” method from the gateway model. Currently, he does not.

Of course, if I specifically capture from the "Administrator" view, he will try to capture, but this should happen immediately after verification (and again, I understand that he should already).

In my gateway model, I have the following (truncated for readability):

<?php
class Example_Gateway_Model_Payment extends Mage_Payment_Model_Method_Cc
{
    protected $_code = 'example';

    protected $_isGateway = true;
    protected $_canAuthorize = true;
    protected $_canCapture = true;
    protected $_canUseInternal = true;
    protected $_canUseCheckout = true;

    // This is an empty block class that extends Mage_Payment_Block_Form_Cc
    protected $_formBlockType = 'example/form_example';

    public function authorize(Varien_Object $payment, $amount)
    {
        Mage::log('Authorizing!');
    }

    public function capture(Varien_Object $payment, $amount)
    {
        Mage::log('** Capturing **');
        // Third-party API stuff would go here, with exceptions being thrown if the gateway determines they've provided an invalid card, etc.
    }

    public function assignData($data)
    {
        Mage::log('Assigning Data');
    }
}

- assignData() validate(), __construct(), . , , .
