Strange, IPhone performSelector on sub-thread doesn't work.

I want to do some action on a thread using the following API, so strange selector poiOneBoxSearch hasn't been invoked, why? Any mistake on the code? Thanks. 

- (void)poiOneBoxSearch{
     [self poiOneBoxSearcWithQueryString:@"coffee" isFinished:YES];
}

- (void)test1{
     NSThread* thread = [[NSThread alloc] init];
     [self performSelector:@selector(poiOneBoxSearch)
               onThread:thread
             withObject:nil
          waitUntilDone:YES];
     [thread release];
}

[self performSelectorInBackground:@selector(poiOneBoxSearch) withObject:nil];

- (void) poiOneBoxSearch{
          @autoreleasepool { 
     [self poiOneBoxSearcWithQueryString:@"coffee" isFinished:YES];
} }

The most important thing that you have to keep in mind is that since this method creates a thread on the given selector, the selector must have an autorelease pool just like any other thread in a reference-counted memory environment.
