How to refresh a rootViewController after saving from a different ViewController

I have a tableview based app with sqlite database and am having difficulty getting the original root view controller to refresh the table after I add a record from a different view controller. I tried adding the object to the array used from rvc and even tried reloading the entire database like I do at the opening of the app. None of these result in the new record showing after clicking save. New record only shows when app is closed and started up again. I am not sure what I'm doing wrong.

- (void) save_Clicked:(id)sender {

ConditionsAppDelegate *appDelegate = (ConditionsAppDelegate *)[[UIApplication sharedApplication] delegate];

//Create a Condition Object.
Condition *c = [[Condition alloc] init];

NSInteger newId = c.getNextConditionId;

Condition *cond = [[Condition alloc] initWithPrimaryKey:newId];

cond.condition_area = txtConditionArea.text;
cond.condition_detail = txtConditionDetail.text;
cond.condition_name = conditionName;

//Add the object
[appDelegate addCondition:cond];
[cond addCondition];

[appDelegate populateFromDatabase];

rvc.conditions = [appDelegate activeConditions];

// UPDATE THE TABLEVIEW
[rvc.tableView reloadData];

// release
[cond release];
[c release];

//Dismiss the controller.
[self.navigationController dismissViewControllerAnimated:YES completion: nil];
}
