I misunderstood your initial question, sorry. For what you are doing both
IC and FC will work. However the data column stores a *reference* to a
hash. By doing hash->{key} = val you are not changing the reference, so
as far as DBIC is concerned the value of the column did not change.
What you need to do is manually invoke[1] or replace the entire hashref
with another hashref.
