How to bind single checkbox value with AngularJS Controller

I have checked question How to bind to list of checkbox values with AngularJS. But this question explains list of arrays and best ways to handle it in Angular controller.

<input type='checkbox' name="filter" checked>

How can we bind value to checkbox to have value as modal 0 when unchecked and 1 when checked? What should be in HTML and Controller?

$scope.filter = 0;
