Testcase [Web Client] KnockoutJS support -> Parent


Have JS file (source: KnockoutJS documentation)
*-*-*-*
function AppViewModel() {
    var self = this;
 
    self.people = ko.observableArray([
        { name: 'Bert' },
        { name: 'Charles' },
        { name: 'Denise' }
    ]);
 
    self.addPerson = function() {
        self.people.push({ name: "New at " + new Date() });
    };
 
    self.removePerson = function() {
        self.people.remove(this);
    }
}
 
ko.applyBindings(new AppViewModel());
*-*-*-*
and HTML file
*-*-*-*
<h4>People</h4>
<ul data-bind="foreach: people">
    <li>
        Name at position <span data-bind="text: $index"> </span>:
        <span data-bind="text: name"> </span>
        <a href="#" data-bind="click: $parent.">Remove</a>
    </li>
</ul>
<button data-bind="click: addPerson">Add</button>
*-*-*-*

Steps:

In HTML file, invoke cc after "$parent." 

Expected result:
people, addPerson() and removePerson() are offered. Try it again, but replace $parent with $parents[0] and then with $root



The required attributes aren't purposed by auto complete.
A ctrl + click on "people" (line 2) correctly open the js file.
