            {model : "Volvo XC90", color : "black"}
        ];

        $scope.checkedColors = function(){
       var checkedArr = $filter('filter')($scope.cars, {checked : true});
       var text = '';
       for(var i = 0 ; i < checkedArr.length ; i++) {
if(text.length != 0){text += ','}
text += checkedArr[i].color;
}
return text;
}

$scope.checkedModels = function(){
       var checkedArr = $filter('filter')($scope.cars, {checked : true});
       var text = '';
       for(var i = 0 ; i < checkedArr.length ; i++) {
if(text.length != 0){text += ','}
text += checkedArr[i].model;
