After you set the new value to your variable, call

InvokeAsync(StateHasChanged);

This will request a re-render of the component.

Hi, for me worked well. I used it at the end of a long function which use a file stream to read some images. My problem was that the variables changes was reflected in web after one other additional action.
(ex: When a function was executed two time, at the first run the web state was not updated, at the second run the web state displayed the state from the first run)
