Not able to load data in view

Question

Hi All
i had created one view based on four different tables.Now to enter the data in load i had successfully created INSTEAD OF TRIGGER on view.But data load into tables but when i try to see data in view then its shows me nothing.
so why my data not load in view but lad into four diff tables.
---VIEW CODE
CREATE OR REPLACE FORCE VIEW "VIEW_WELL_GENERATOR_FORM" ("WEL_PK", "STA_PK", "PER_PK", "FAC_PK", "WELL_TYPE", "WELL_TYPE_DATE", "OPER_STATUS", "STATUS_DATE", "CLASS", "SITE", "FAC_TYPE", "AUT_STATUS") AS
