Resetting the values of the dynamically generated table data

I am working on a web form wherein I am retrieving data from database using ajax call and displaying it in a dynamic table each row in a table has a checkbox which is checked and unchecked based on some value in the database. Next I want to clear only values of the table and then when i click on another ajax call button the values should get populate in the previously generated table with all the checkbox unchecked. how do I achieve this or is there any other way to achieve this. even a small lead on this would be helpfull. thank you.
