Custom Datagrid refresh after Insert

I have a Datagrid and I implemented new methods.
I inserted the "this.load ()" event for the delete operation and the grid was updated.
However, when I access the screen to add a new item, "this.load ()" does not work. I put "this.load ()" in the "LoadData" event.
What could be wrong?

Check the CRUD pages created by Radzen for reference.

It was the first thing I did.
But I found nothing different.

The reload code is not in the add page. It’s in the main page that will open the add page.
