chart doesn't auto update on value changes

[ramarro123]

chart value doesn't get updated if option object change

it's possible to fix this behaviour?

@ramarro123 are you sure you're providing new option object (not a changed one)?

See comments in #3 - you need to provide a new object (so deep clone it if needed, recreate it, whatever), otherwise Angular's Change Detection doesn't know something changed (same object, so no need for updates, right?).
