navigation button don't work as what it should be
currently I'm developing a program that have 2layer of table, which the value will be take from JSON, I've done almost all, but the navigation part hinder me, the program will have a list of data in the 1st view, then when user click (let say) option 1, it'll switch view to the next table with some option A,B,C,etc. But so far, when I click the option 1, it never switch view. Although the data inside the table data source are those of the 2nd table. Oh, I use the push method to switch the view.

RootViewController *rvController  = [[RootViewController alloc] initWithNibName:@"RootViewController" bundle:[NSBundle mainBundle]];
    [self.navigationController pushViewController:rvController animated:NO];


I try to use [self.tableview reloadData], to reload the tableview(hoping to have the correct value shown in the table), it never shown. 
Any help is appreciated. 
Thanx in advance.
