Hi Kumar,
Iam sorry kumar, can i ask you one thing have you really Checked this component and the view you specified above by putting breakpoints?? 
I am very much confident about my answer and check that component once when you are free.
DO_INIT_CONTEXT will trigger only once i.e for the first time( before displaying the screen ). Do_validate_input and do_finish_input will trigger after the user input ( i.e after the view gets displayed and user gives some input or makes some action ).
So Do_init_context will never trigger after the do_finish_input.. 
Regards,
Bala.
