Pglogical replication sets not working as expected

I am trying to setup up pglogical replication. I have a table which has around 4 rows in the provider server.

=========
employee_id |     visitor_email     | vistor_id |        date         |             message          
-------------+-----------------------+-----------+---------------------+--------------------------
       1 | roshan@gmail.com      |         1 | 2016-08-24 00:00:00 | This is the first test.
       2 | roshan@myrepublic.net |         2 | 2016-08-24 00:00:00 | This is the second test.
       3 | roshan@myrepublic.net |         3 | 2016-08-24 00:00:00 | This is the third test.
       4 | roshan@myrepublic.net |         4 | 2016-08-24 00:00:00 | This is the fourth test.
  ===============================

After creating the above mentioned table. I have created a replication set in the provider . Then I configured the subscriber node and the subscription. Ideally, I should see the 4 rows from the provider table in my subscriber, but I am only seeing the table structure in subscriber, not the data. If I add a new row in the provider table as follows

INSERT INTO employees (employee_id, visitor_email, date, message) VALUES (5, 'roshan@myrepublic.net', current_date, 'This is the fifth test.'); 

Now, I am able to see the last added row in my subscriber table. All the other 4 rows which were added in the beginning are still missing. What am I doing wrong here?

Does it mean that only the data which was created after the creation of replication_sets will be considered? How to add the whole content of a table to a replication set.?

Any help would be much appreciated.?
