How to solve "no such table" error with Sqlite3 in iphone?

I am currently experimenting with SQLite on the iOS, but something seems wrong, I can't get to my table, even though I know it exists. The .sqlite file was created using Following code for ,Then I inserted one record into it using the my textfeild but when i clicked save button . However,I get a "no such table" error!

Here's the code:

-(int) createTable:(NSString*) filePath
    {
        sqlite3* db = NULL;
    int rc=0;

    rc = sqlite3_open_v2([filePath cStringUsingEncoding:NSUTF8StringEncoding], &db, SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE, NULL);
    if (SQLITE_OK != rc)
    {
        sqlite3_close(db);
        NSLog(@"Failed to open db connection");
    }
    else
    {
        char * query ="CREATE TABLE IF NOT EXISTS GrowthExamination ( id INTEGER PRIMARY KEY AUTOINCREMENT, date  TEXT,day  TEXT, ga INTEGER, weight INTEGER,HC INTEGER,lenght INTEGER )";
        char * errMsg;
        rc = sqlite3_exec(db, query,NULL,NULL,&errMsg);

        if(SQLITE_OK != rc)
        {
            NSLog(@"Failed to create table rc:%d, msg=%s",rc,errMsg);
        }

        sqlite3_close(db);
    }

    return rc;

}
-(NSString *) getDbFilePath
{
    NSString * docsPath= NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES)[0];

    return [docsPath stringByAppendingPathComponent:@"GrowthExamination.db"];
}

-(void)saveButtonClicked:(UIButton *)sender {
int rc= [self insert:[self getDbFilePath] withDate:[ReadindDateButton titleForState:UIControlStateNormal] Day:ReadingDayTextFeild.text GA:(long)GAInt Weight:(long)weightInt HC:(long)HCInt Length:(long)lengthInt];
        if(rc != SQLITE_OK)
        {
            [self showMessage:@"ERROR" withMessage:@"Failed to insert record"];
        }
        else
            [self showMessage:@"SUCCESS" withMessage:@"Record is added"];
}
