i would like to change an action from an existing button to a func in my MainTableViewController. If i create the button programmatically, its not a problem - but with an existing button from Storyboard-Editor the method will not be called.

Any ideas what is wrong here?

```
class SignatureTableViewCell: UITableViewCell {

    @IBOutlet weak var signatureButton: UIButton!

    var formVC:FormTableViewController!

    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }

    override func setSelected(selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }

    override init() {

        super.init()

        self.signatureButton.addTarget(formVC, action: "signatureButtonPressed:", forControlEvents: .TouchUpInside)

    }

```
