This method is used to remove the error :

    For this use the result of the function as the click event  because the parameter is a function reference.

    The function call which is  passed automatically include the data for that item so  manual passing is not required  :

<div data-bind="foreach: Contacts">
    <a data-bind="click: $parent.Foo, text: Name">link</a>
</div>

The details is provide in the click documentation.

    The  function reference is related to the  click binding‘s parameter . So try to wrap the call into an anonymous function:

<div data-bind="foreach: Contacts">
    <a data-bind="click: function() { $parent.Foo($data); }, text: Name">link</a>
</div>

    So , During pass the extra arguments into the click binding the user should  wrap it to make a function. 

    The working of  <button data-bind=”click: AddContacts”> expression is due to the user straightly referencing the AddContacts function there.
