Set the sub-category in the controller:
$this->set('sub_category', ...
then, in your element:
$this->requestAction("category/index/${sub_category}");
However, I'm not certain that I understand what you want to do, so there may
be a better way to achieve your goal. Specifically, I don't understand why
you want to call the index() method here. If you use the above example, your
method will expect a parameter for sub_category. For example:
$this->requestAction("category/foo/${sub_category}");
In the controller:
function foo($bar)
{
return $bar;
}
