rollback a nested transaction in trigger - triggers

Question

I have a following situation.
I have a table with trigger for insert.
When I insert a row in it, from this trigger I want to insert some rows into a second table.
For each of these rows I want to do it in it's own transaction in case something go wrong.
I want to have original row in first table and all rows (these withous errors) in the second.
A little code to reproduce:
create table test(id int primary key identity(1,1),name nvarchar(10))
create table test2(id int primary key identity(1,1),
state char(1) check (state in ('a','b')))
go
create trigger test_trigger on test for insert
as
begin
declare #char char(1)
declare curs cursor for (
select 'a'
union
select 'c'
union
select 'b')
open curs
fetch next from curs into #char
while ##FETCH_STATUS = 0
begin
begin try
begin transaction
insert into test2(state)
select #char
commit
end try
begin catch
print 'catch block'
rollback
end catch
fetch next from curs into #char
end
close curs
deallocate curs
end
go
insert into test(name) values('test')
select * from test
select * from test2
go
drop table test
drop table test2
So for the sample data from this snippet, I want to have a row with 'test' in test table and two rows in the test2 table ('a' and 'b').
How can I write a code for that?

Looks like finally I got it to work.
Corrected trigger code:
create trigger test_trigger on test for insert
as
begin
declare #char char(1)
set xact_abort off
declare curs cursor for (
select 'a'
union
select 'c'
union
select 'b')
open curs
fetch next from curs into #char
while ##FETCH_STATUS = 0
begin
save transaction t
begin try
insert into test2(state)
select #char
end try
begin catch
print 'catch block'
rollback transaction t
end catch
fetch next from curs into #char
end
close curs
deallocate curs
end
