Rxswift更新Tableview单元格值

Question

I am able to bind an Observable sequence of data to a table. Now lets say i have a button on each cell which on click changes the label of that cell to new value. How to do this ?

I have done so far as follows

I have created an @IBAction for that button in the cell pointing class

then i am doing

label.text = "new text"

but when i scroll down then scroll up, the label show previous value not the new value

previously when i use array and set each value to a cell i used to update that array item and called tableview.reloadData .

how can i do this in RxSwift??

I have done so far

tableview.dataSource = nil (then)
myData.bindTo ... (bind again)

This does not seem to me the right way. so what is the appropriate way to deal with this??

I am able to achive this with RxSwiftCommunity Action

https://github.com/RxSwiftCommunity/Action

ViewController

variable.asObservable().bindTo(mytable.rx.items(cellIdentifier: "cell")) { (row, person, cell) in
            if let cellToUse = cell as? TableViewCell {
                cellToUse.person = Variable(person)
                cellToUse.button1.rx.action = cellToUse.action
            }
            }.addDisposableTo(disposeBag)

and in cell

class TableViewCell: UITableViewCell {

    @IBOutlet weak var label1: UILabel!
    @IBOutlet weak var label2: UILabel!
    @IBOutlet weak var button1: UIButton!

    let disposeBag = DisposeBag()
    let action = CocoaAction { input in
        return .just(input)
    }

    var person : Variable<Person>!{
        didSet {
            self.updateUI()
        }
    }

    private func updateUI(){
        person.asObservable()
            .subscribe(onNext: {
                person in
                let name : Observable<String> = Observable.of(person.name)
                let age : Observable<String> = Observable.of("\(person.age)")
                _ = name.bindTo(self.label1.rx.text)
                _ = age.bindTo(self.label2.rx.text)
            }).addDisposableTo(disposeBag)

        action.elements
            .asObservable()
            .subscribe(onNext: {
                _ in
                self.label2.text = "asd"

            }).addDisposableTo(disposeBag)
    }
}

like before not sure if this is the right way but it worked for me

thanks to ( https://rxswift.slack.com/messages/@fpillet ) for showing me the way
