Blazor components folder issue

I am working on a Blazor hybrid project and have a component called ArraySelector.If I place the component in a subdirectory BaseComponents as shown below

And set

The @onclick event is not recognize and gives an error on execution.

If I copy my component in a subdirectory under components,

then the @onclick is recognized and it works.

So I wonder what could be the reason of this behavior?What am I doing wrong?
