javascript - KnockoutJS: Commented foreach with "afterAdd"

Question

The goal

Make this possible:

<!-- ko foreach: { data: products, afterAdd: highlightIt } -->
<li>
   [...]
</li>
<!-- /ko -->

The problem

The syntax is wrong. It seems to be possible only with data-bind attribute, like this:

<ul data-bind="foreach: products, afterAdd: highlightIt">
    <li>
        [...]
    </li>
</ul>

What is happening, eventually?

Nothing. Console displays no errors, but Knockout cannot work with the foreach because its do not know that comment is a foreach.

Someone have any idea?
