Need help in implementing Refresher add-on.

i m testing to implement refresher on my project, but for the understanding of the refresher i m simply populating some record in vaadin table and on the same page i m updating that same table via two text fields records are successfully modified, but table component of vaadin dont show the updated record for that purpose after some R&D i found a solution named Refresher add-on, now i did copy the jar file and recompilation of widget sets, now i can able to create Refresher object but having no clue what to do next, if somebody tell me how to refresh my table on each update via refresher i will be very thankful to him. Thanks in Advace
