perform Segue With Identifier from a dynamic collectionViewCell in a tableViewCell of a dynamic tableView, swift

I have in a dynamic tableView, a dynamic collectionView in one of the tableViewCell.

In every collectionViewCell, there is a button which should be the trigger for the segue.

I tried with the following code, but the app crash :

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver (<Okm.bienController: 0x7fc8b0cfb1a0>) has no segue with identifier 'extend''

The segue identifier in my storyBoard is 'extend'.

 class photoCell: UITableViewCell, UICollectionViewDelegateFlowLayout, UICollectionViewDelegate, UICollectionViewDataSource {
    ...

    func extendFunc(sender : UIButton) {

       bienController().performSegueWithIdentifier("extend", sender: sender.tag)
    }
}


class bienController : UIViewController, UITableViewDelegate, UITableViewDataSource {

...

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "extend" {
            let backItem = UIBarButtonItem()
            backItem.title = ""
            navigationItem.backBarButtonItem = backItem

            let extendView = segue.destinationViewController as! extendController
            extendView.image = image[sender]

        }
    }
}

Do you know how I can do it?

Thank you!!!

EDIT

enter image description here

the term bienController().performSegueWithIdentifier(...) is it correct? Can I call a function of my Controller from a UICollectionCell ?

EDIT

I tried this :

 func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        if tableView == self.tableViewTwo {
            self.segue()
          // self.performSegueWithIdentifier("image", sender: nil)
        }
    }

    func clickExtend(sender:Int){
        print(sender) //print the correct tag!
       self.segue()
    }

    func segue(){
         self.performSegueWithIdentifier("image", sender: nil)
    }

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

        if segue.identifier == "image" {
            let backItem = UIBarButtonItem()
            backItem.title = ""
            navigationItem.backBarButtonItem = backItem
           // print(sender)

           let extendView = segue.destinationViewController as! extendController
           extendView.image = UIImage(named: "maison")

        }
    }
}

I linked the function clickExtend() with the button of my collectionCell. The segue works when it somes from didSelectRowAtIndexPath, but when I click on the button extend it crashes with the same error : 'Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver () has no segue with identifier 'image'''

I don't get it..

( I changed the segue identifier for 'image')

You have to use delegates. I had this problem before,and I used protocol and delegates to solve It and perform a segue with identifier.

like Fernando Cani says

try change bienController().performSegueWithIdentifier("name")

to

self.performSegueWithIdentifier("name")

It looks like the identifier is either not connected properly or its is not set as "extend" because the error message says (has no segue with identifier 'extend')

Check if the segue is coming out of the cell or the viewController. Maybe it is that.
