UIRefreshControl is not hiding after refresh. iOS

Question

I am using UIRefreshControl in my table view. I have initiated refresh control in viewDidLoad:

    UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];
    [refreshControl addTarget:self action:@selector(handleRefresh:) forControlEvents:UIControlEventValueChanged];
    self.refreshControl = refreshControl;
    [self.bestDealsTableView addSubview:self.refreshControl];

I have a target method for scrolling:

-(void) handleRefresh:(UIRefreshControl *) refreshControl{
    [self performSelector:@selector(updateDealsList) withObject:nil withObject:nil];
}

updateDealsList method:

- (void) updateDealsList {
    self.dealsService = [[BestDealsService alloc] initServiceWithDelegate:self isLocalCall:NO];
    [self.dealsService fetchBestDeals];
}

In my service response method:

    [self.refreshControl endRefreshing];
    self.isTableViewInRefreshMode = YES;
    [self.bestDealsTableView reloadData];

Now, I have two issues: 1. My refresh Control is not hiding on success response from my service. 2. If I pull table view down, I can see a refresh control, but if I scroll down again, I see a new one below the previous one.

Note: I am using custom TableViewCell

This is how I fixed it:

// Pull To Refresh Code
if(self.refreshControl == nil){
    UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];
    [refreshControl addTarget:self action:@selector(handleRefresh:) forControlEvents:UIControlEventValueChanged];
    self.refreshControl = refreshControl;
}
[self.myTableView addSubview:self.refreshControl];
