I have a custom `UIImage` within my cell that I need to change when `didSelectRowAtIndexPath` is called. For some reason the image isn't changing, and I think it's because of my cell declaration inside the method. 

```
class CustomCell: UITableViewCell {

    @IBOutlet weak var indicator: UIImageView!

}

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

        var cell = tableView.dequeueReusableCellWithIdentifier("CustomCell", forIndexPath: indexPath) as! CustomCell

        cell.indicator.image = UIImage(named: "newImage")

}

```

How can I change my `UIImage` to "newImage" when the cell is clicked?
