When you have a checkbox, not necessary that just ‘ture‘ & ‘false‘, you might have ‘yes‘, ‘no‘, ‘1‘, ‘0‘:
There is how to use ng-true-value and ng-false-value with ng-checked for checkbox:
<input type="checkbox" ????ng-model="checkbox" ????ng-true-value="1" ????ng-false-value="0" ????ng-checked="checkbox == 1" />
$scope.$watch(function(){ ???return $scope.checkbox;}, function(){ ???$scope.checkbox = Number($scope.checkbox); ???console.log($scope.checkbox, typeof $scope.checkbox);},true);[AngularJS] ng-ture-value & ng-false-value
