Pushing View Controller from Child View Controller

I am developing an application where there is a container view and I am attempting to push it into another view controller from the parent. When I try pushing the navigation bar stays the same of the parent view controller rather than turning into the navigation bar of the newly pushed controller. Here is a animation of what is going wrong. enter image description here
How would I make the navigation bar change to the new view controller. (On a side-note the keyboard doesnt seem to dismiss either)

Parent VC

- (UIViewController *)carbonTabSwipeNavigation:(CarbonTabSwipeNavigation *)carbonTabSwipeNavigation
viewControllerAtIndex:(NSUInteger)index {
if(index == 0){
SearchChildVC *svc = [[SearchChildVC alloc] init];
svc.results = nil;
[self searchTop:_searchBar.text];
[[NSNotificationCenter defaultCenter] postNotificationName:@"reload_data" object:self];
return svc;
}else if(index == 1){
SearchChildVC *svc = [[SearchChildVC alloc] init];
svc.results = nil;
[self searchPeople:_searchBar.text];
[[NSNotificationCenter defaultCenter] postNotificationName:@"reload_data" object:self];
return svc;
}else if(index == 2){
SearchChildVC *svc = [[SearchChildVC alloc] init];
svc.results = nil;
[self searchOrganizations:_searchBar.text];
[[NSNotificationCenter defaultCenter] postNotificationName:@"reload_data" object:self];
return svc;
}
return [[SearchChildVC alloc] init];
}


Child VC

- (void)tableView: (UITableView *) tableView didSelectRowAtIndexPath: (NSIndexPath *) indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
PFObject *data = self.results[indexPath.row];
if (data[@"fullName"]) {
// User Cell
[self resignFirstResponder];
ForeignProfileVC *fvc = [[ForeignProfileVC alloc] init];
//fvc.userId = ;
[self.navigationController pushViewController:fvc animated:YES];
}else{
// Organization Cell
[self resignFirstResponder];
OrganizationViewController *ovc = [[OrganizationViewController alloc] init];
ovc.object = (NSDictionary *)data;
[self.navigationController pushViewController:ovc animated:YES];
}
}


New VC

-(void)setupUI {
self.view.backgroundColor = [UIColor whiteColor];
NSString *organizationTitle = [self.object objectForKey:@"Name"];
[self.navigationItem setTitle:organizationTitle];
self.view.backgroundColor = [UIColor whiteColor];
[self.navigationController.navigationBar setTitleTextAttributes:
@{NSForegroundColorAttributeName:[UIColor whiteColor],
NSFontAttributeName:[UIFont fontWithName:@"OpenSans-Semibold" size:18]}];

UIButton *barButton = [UIButton buttonWithType:UIButtonTypeCustom];
[barButton setTitle:@"" forState:UIControlStateNormal];
[barButton setBackgroundImage:[UIImage imageNamed:@"closeIcon"] forState:UIControlStateNormal];
[barButton addTarget:self action:@selector(didTapClose:) forControlEvents:UIControlEventTouchUpInside];
barButton.frame = CGRectMake(0.0f, 0.0f, 15.0f, 15.0f);
UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:barButton];
self.navigationItem.leftBarButtonItem = barButtonItem;

UIButton *postButton = [UIButton buttonWithType:UIButtonTypeCustom];
[postButton setTitle:@"" forState:UIControlStateNormal];
[postButton setBackgroundImage:[UIImage imageNamed:@"gearIcon"] forState:UIControlStateNormal];
[postButton addTarget:self action:@selector(didTapGear:) forControlEvents:UIControlEventTouchUpInside];
postButton.frame = CGRectMake(0.0f, 0.0f, 18.0f, 18.0f);
UIBarButtonItem *postButtonItem = [[UIBarButtonItem alloc] initWithCustomView:postButton];
self.navigationItem.rightBarButtonItem = postButtonItem;
}

Answer

pushViewController will reuse the same navigation controller. You can do either presentViewController which will present a new view controller, or handle the change of your search bar by yourself. For example, in new view controller will appear do something like set searchbar hidden/ set navigationbar to some other style.
