This code:

Answer 1

A simple solution that works on Angular 1.3+ is:

Template

Controller

  let lastChecked = null
  $scope.radioCheckUncheck = function (event) {
    if (event.target.value === lastChecked) {
      delete $scope.forms.selected
      lastChecked = null
    } else {
      lastChecked = event.target.value
    }
  }

It's similar to the above solution, but maintains its own copy of the previous selection.
