iPhone Sqlite database, data does not save inside database file

Hi I'm have a problem with my database:

1.Files are unable to be saved inside the database itself

Whenever i try saving something inside the app itself, the data does not save inside the db file, i try looking for guides and help but still it does not work

These is my .h file

@interface feedback : UIViewController

@property (nonatomic, strong) NSString *databasePath;
@property (nonatomic) sqlite3 *feedbackDB;

@property (weak, nonatomic) IBOutlet UITextField *nameInput;

@property (weak, nonatomic) IBOutlet UITextField *phonenoInput;

@property (weak, nonatomic) IBOutlet UITextField *commentInput;

@property (weak, nonatomic) IBOutlet UILabel *status;

- (IBAction)saveData:(id)sender;
- (IBAction)searchUser:(id)sender;

my .m file

#import "feedback.h"

@interface feedback ()

@end

@implementation feedback

   - (void)viewDidLoad {

                 initWithString: [docsDir stringByAppendingPathComponent:

NSFileManager *filemgr = [NSFileManager defaultManager];

if ([filemgr fileExistsAtPath: _databasePath ] == NO)
{

    const char *dbpath = [_databasePath UTF8String];

    if (sqlite3_open(dbpath, &_feedbackDB) == SQLITE_OK)
    {

        char *errMsg;
