reloadMessagesData is not calling table functions after being called

[DanlgArmstrong]

I have a viewController defined as:
@interface MessageDetailView : AMMessageComposerVC<AMMessageComposerDatasource, AMMessageComposerDelegate>

On viewDidLoad I call a function to load my messages data into:
@Property NSMutableArray *jsonArray;

Here is my loading func:

• (void)viewDidLoad
  {
  [super viewDidLoad];
  // Do any additional setup after loading the view.

  self.amDataSource = self;
  self.amDelegate = self;
  [self getMessages:@""]; // load up jsonArray
  }

• (void) getMessages:(NSString *) after {
  .... load data ...
  [self performSelectorOnMainThread:@selector(reloadMessagesData) withObject:nil waitUntilDone:NO];
  }

Now the reloadMessagesData is called - I set a breakpoint in that function and it does:
[self.messageTableView reloadData];

But it seems NOT to cause the table to reload. I had breakpoints set in
-(NSInteger) numberOfMessages
{
return jsonArray.count;
}

BUT the only time numberOfMessages fires is BEFORE I have a chance to load jsonArray. It SHOULD also be firing after I call reloadMessagesData.

Do you have any idea why this would not happen?
