UITableview on nib (view) doesn't reload (Objective-C)

Question

I wanna reload some data in my FAQViewcontroller. The tableview is placed in a nib file (view) which is loaded with the Viewcontroller, called this way:

FAQViewController *vc = [[FAQViewController alloc] initWithNibName:@"FAQViewController" bundle:nil];
            [self presentViewController:vc animated:YES completion:nil]; 

In viewDidLoad of FAQViewcontroller, the tableview is displaying the right way (I see the separator lines and when I'm changing the backgroundColor, it is working well). But there's no information to display yet, so the cells are empty (as expected).

- (void)viewDidLoad {
[super viewDidLoad];

self.tableView.delegate = self;
self.tableView.dataSource = self;

[self.tableView registerNib:[UINib nibWithNibName:@"FAQCell" bundle:nil] forCellReuseIdentifier:@"FAQCell"];

if (self.faqData == nil || [_faqData count] == 0) {
    dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void){
        [[DataModel sharedInstance] getFrequentlyAskedQuestions:^(NSError *error) {

        }];
    });
}
}

When the network call is done, this function in the FAQViewcontroller is called:

- (void)setFaqData:(NSArray *)faqData {

_faqData = faqData;
NSLog(@"%@", _faqData);

dispatch_async(dispatch_get_main_queue(), ^() {
    [self.tableView reloadData];
});
}

But reloadData is doing nothing. The numberofrowsinsection isn't called.

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return _faqData.count;
}

I don't know what to do about it. Never had this before (normally I code in Swift, maybe I forget something in Objective-C)?

Does anyone know what I'm doing wrong?

Thank you very much!

Could you try making tableView as a strong reference? something like:

@property (nonatomic, strong) IBOutlet UITableView *tableView
