Jmeter UI POST data not getting updated in mysql

I am trying my first J meter UI testing setup. I have a simple page with two textboxes where I input some text and I am trying to see this data is getting saved in the database. I record the actions using blazemeter and export to Jmeter format. When I import the script and test in Jmeter, none of the textbox data is getting updated in the database. But one session variable which is nothing but and id, and another data[todays date] is getting saved in the database. When I look into the Jmeter all POST data is visible there. Any opinion on why POST data is not getting saved in the mysql table.

I have tried this with local host and actual server. Both giving same result.
