UITableView in a UIViewController, problem with datasource?

Question

Hi All,

I have this:

@interface HomePage : UIViewController<UITableViewDelegate, UITableViewDataSource> {
 UITableView *myTable;
 NSMutableArray *data;
}
@property (nonatomic, retain) IBOutlet UITableView *myTaböe;
@property (nonatomic, retain) NSMutable *data;

and then I have connected via IB the myTable with datasource and delegate in "File's Owner". I am then initializing data to an empty array in the viewDidLoad method.

After I perform a HTTP call to retrieve some data, add items to the data and:

int i= 0;
    while(barfoo is true){
      [data insertObject:r atIndex:i];
      NSArray *insertIndexPaths = [NSArray arrayWithObjects:[NSIndexPath indexPathForRow:i  inSection:0],nil];
      UITableView *tv = (UITableView *)self.myTable;
      [tv beginUpdates];
      [tv insertRowsAtIndexPaths:insertIndexPaths   withRowAnimation:UITableViewRowAnimationRight];
      [tv endUpdates];
    i++;
    } 

but nothing happens..... why?
