mdCheckbox: wrong display state when using ngChecked

[ngraef]

CodePen example: http://codepen.io/anon/pen/zxWrGP?editors=101

In the example, ngChecked and ngClick are used to track a list of multiple selected items. The mdCheckboxes display correct state when the model is manipulated by the standard checkboxes. However, after interacting with the mdCheckboxes, their display state is reversed. Using the standard checkboxes again fixes the mdCheckbox state.

Confirmed, there's a not operator on the checked var inside the apply:

checkbox.js:123

scope.$apply(function() {
      checked = !checked;
      ngModelCtrl.$setViewValue(checked, ev && ev.type);
      ngModelCtrl.$render();
});

Removing the ! has fixed it for me, don't know what the intention of it was and I unfortunately don't have the time to take a more in depth look, sorry! Hope this helps though.

Thanks guys.

@ThomasBurleson It doesn't look like 942d0b9 fixed the demo in my initial post.

@ngraef - switch ng-checked to ng-model="exists(item, selected)" and all works.

I have re-opened to investigate issues with ng-checked.
