Repeat tableview cell issue while scrolling on iphone

There are 5 cells, and each cell has one dynamic label. cell height is defined as the contents of the label using the heightForRowAtIndexPath method. Now 3 cells are displayed. When I scroll for the following cells, cellForRowAtIndexPath is called once, and at the output any cell (4 OR 5) is displayed correctly, and the other has the 1st cell content (repeated). Is there any solution to fix this? The cellForRowAtIndexPath method should be called 2 times. I correctly defined sections and lines.

{
    static NSString *kCustomCellID = @"CustomCellID";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:kCustomCellID];
    if (cell == nil)
    {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:kCustomCellID] autorelease];
    }

    cell.textLabel.text = [self.dataArray objectAtIndex:indexPath.row];
    cell.detailTextLabel.text = [self.dateFormatter stringFromDate:[NSDate date]];

    return cell;
}
