How do I create EventCallback in Blazor WASM

Radzen Studio Blazor Server
1

I have a radzen button in a radzen form and I want to create a control that will call a few methods. To do this I need to perform an parameter that us an EventCallback.

I cannot figure the logic for the Click event of the button or the Submit of the form.

I am using Visual Studio 2019.

EG: Submit="@(() => CallMyMethod.InvokeAsync)"

In C# methods are executed usually with () at the end - not sure how this is related to Radzen or Radzen Blazor components.
