Connecting NodeJS app to SignalR (with .NET Core 3)

I have a server running SignalR using .NET Core 3. The project was started with the template and I followed a guide (https://docs.microsoft.com/en-gb/aspnet/core/tutorials/signalr?tabs=visual-studio&view=aspnetcore-3.0).

Text does not show in html input date on a modal form

Problem: the Enter Date field of the modal form does not populate with data. I have a modal form that opens up when I click on Edit on a record line.

I have two lists (list-left and list-right) prepared and populate. Then I have this JS code to move elements from one list to another. And it works fine. But honestly I don’t know how to pass the result back to codebehind when user clicks the submit button on the form?
