I did something like this but I do not know the best solution.

in html

ng-click="deleteMasraf(item, m,$parent.$index)"

in controller

$scope.deleteMasraf = function (item,m,parentIndex) {

    item.dosya[parentIndex].masraf.splice(item.dosya[parentIndex].masraf.indexOf(m),1);
    $scope.customer = item;
    $scope.customer.put();

};
