angular js multiple checkboxes filters on multilevel JSON

Hey guys I found this one on multiple checkboxes filter: angular js multiple checkbox with custom filters

I have a similar problem but a multilevel JSON. Something like this: http://ift.tt/1CSbBY6

Especialy this part is my problem:

$scope.searchFilter = function(row){
        var mercChecked = getChecked($scope.merchantCheckboxes);
        var brandChecked = getChecked($scope.brandCheckboxes);
        if(mercChecked.length == 0 && brandChecked.length == 0)
            return true;
        else{
            if($scope.merchantCheckboxes[row.MerchantName])
                return true;
            else{
                return row.BrandList.split(/,\s*/).some(function(brand){
                    return $scope.brandCheckboxes[brand];
                });
            }
        }
    };

Any ideas?
