it should still fix some issue I have a ViewModel from which I want to update my View. The ViewModel has properties that utilize a PropertyChangedEventHandler to dynamically update the elements on my view. , you can create a binding in code
code :
myImage.SetBinding(Image.SourceProperty, "BindingPath");

Dynamically created elements from codebehind need to be inserted between specific elements

may help you . I created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript. , Perhaps look at using a PlaceHolder control..

hop of those help? I am trying to use Data binding to bind an ObservableCollection to the ItemsSource of a DataGrid, as I learn about WPF and stuff.
code :
<Window.DataContext>
    <local:MainWindow/>
</Window.DataContext>
this.DataContext = this;
<Window DataContext="{Binding RelativeSource={RelativeSource Self}}">
</Window>

will be helpful for those in need To bind event for future elements I use:
$(document).on('click', '.wrapper2 .incrementButton'.....
code :
$(function() {
  // wrapper1 related -- it works
  var $wrapper1 = $('.wrapper1');
  var $number1 = $wrapper1.find('.number');
  $wrapper1.on('click', '.incrementButton', function () {
    var currentVal = parseInt($number1.html(), 10);
    $number1.html(currentVal + 1);
  });


  var $wrapper2 = $('.wrapper2');

  $wrapper2.append('<div class="foundation"></div>');

  var $foundation = $wrapper2.find('.foundation');
  var htmlContent = '' +
      '<div class="arithmetic">' +
      '    <div class="number">1</div>' +
      '    <div class="incrementButton">+ 1</div>' +
      '</div>';
  $foundation.append(htmlContent);

  var $number2 = $wrapper2.find('.number');
  $(document).on('click', '.wrapper2 .incrementButton', function () {
    var currentVal = parseInt($number2.html(), 10);
    $number2.html(currentVal + 1);
  });
});
.wrapper1, .wrapper2 {
  background-color: #E8EAF6;
  padding: 1em;
  width: 12em;;
  margin: 1em;
}
.foundation {
  background-color: #9FA8DA;
  padding: 1em;
}
.arithmetic {
  background-color: #5C6BC0;
  padding: 1em;
  overflow: hidden;
}
.number {
  width: 1.5em;
  height: 1.5em;
  text-align: center;
  line-height: 1.5;
  background-color: white;
  float: left;
  color: #3949AB;
  margin-right: 1em;
}
.incrementButton {
  overflow: hidden;
  height: 1.5em;
  line-height: 1.5;
  text-align: center;
  background-color: #3949AB;
  border: 1px solid white;
  color: #E8EAF6;
}
.incrementButton:hover {
  cursor: pointer;
  background-color: #283593;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>


<div class="wrapper1">
    <div class="foundation">
        <div class="arithmetic">
            <div class="number">1</div>
            <div class="incrementButton">+ 1</div>
        </div>
    </div>
</div>

<div class="wrapper2"></div>
Binding between C++ and QML with dynamic created tab elements

With these it helps As the GrecKo recommended in the comment I've used the Repeater inside TabView and defined for it a model.
The TabView with Repeater looks like this:
code :
TabView {
    id: tabRoot
    Repeater {
        model: ConnectionModel
        delegate: Tab {
            title: connection.name
            Client {
                address connection.address
                received: connection.received
            }
        }
    }
}
QApplication app(argc, argv);
QQmlApplicationEngine engine;
// Create instace of ConnectionModel
ConnectionModel model;
// Assasign the model instance to the QML context property "ConnectionModel"
engine.rootContext()->setContextProperty("ConnectionModel", &model);
// ...
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

return app.exec();

To fix this issue each is not an event so cannot use with .on. Try below function to iterate cards
code :
 $('.container').find(".card").each(function() {
       var toggle = $(this).text().length > 16;
       var collapseGroup = $(this).closest('.collapse-group');
       collapseGroup.find('.btn').toggle(toggle);
    });
