Title: Nest Form Bug

1."data-region_target" incorrect when used in nest form.
e.x: @object_name = "person[address]"
"data-region_target" should be "person_address_city" in province select, so, object should sub(/\[/, "_").sub(/\]/, "")
2.no default selected value in nest form
As select method in Rails FromBuilder, the options should equalobjectify_options(options)
