after seraching i have to press screen again to load the new data for iphone why??

Question

when i clikc the serach button i can see the new data behind but i have to click on screen or any other button to load the new data .. is it possible to see new data just when search button goes down

i am doing this when serach button is cliked

[self.tableView reloadData]; searchBar.text = @"";

i think somehow its cause of overlay :(

if i add this after reload data searchBar.text = @"."; then after serahing it just display new data but while scrolling down 1 more static replica is there behind
