How to access $parent or $parents[] in knockout viewmodel click event?

Question

I've got a situation where I'd like to notify a grandparent or $parents[1] of a click event that occurs in a sub viewmodel. So basically I'd like to be able to do this

self.$parents[1].actionTaken 

I think this doesn't work because of binding context vs viewModel but I'd like to hear if anyone has an ideas on the correct way to do something like this. Thanks

 self.save = function () {       //do stuff to self first, then        self.$parents[1].actionTaken();  }; 

Answer 1

Or use the bind trick

data-bind="click: $parent.foo.bind($parent)" 

Now when you access your foo function the this keyword will point to the parent context.

foo: function(child) {    this.children.remove(child); }
