Observablecollection binding not updating

Here comes another feature of Native Script binding - object or value binding.

The second parameter is the expression that will be evaluated.Generally, almost every UI control could be bound to a data object (all Native Script controls are created with data binding in mind).After your code has met the following requirements, you can use data-binding out of the box.And the binding of the Label is set to one-way in order to propagate changes only from the code to the UI.// binding the Text Field const text Field Binding Options = ; target Text Field.bind(text Field Binding Options, source); // binding the Label const label Binding Options = ; target Label.bind(label Binding Options, source); import from "ui/core/bindable"; // binding the Text Field const text Field Binding Options: Binding Options = ; target Text Field.bind(text Field Binding Options, source); // binding the Label const label Binding Options: Binding Options = ; target Label.bind(label Binding Options, source); To create a binding in XML, a source object is needed, which will be created the same way, as in the example above (Two-Way Binding in Code).
