Answer 1

I have created directive for that, seems to work fine:

angular.module('app').directive('cdTrueValue', [function() {
  return {
    restrict: 'A',
    require: 'ngModel',
    link: function(scope, element, attrs, ngModel) {
      ngModel.$parsers.push(function(v){
        return v ? scope.$eval(attrs.cdTrueValue) : scope.$eval(attrs.cdFalseValue);
      });

      ngModel.$formatters.push(function(value) {
          return value === scope.$eval(attrs.cdTrueValue);
      });
    }
  };
}]);
