Dynamic hint not updating

Hi I have a hint on a field that changes depending on a select field. I have this working in another app but cant seem to get it working in this one and for the life of me I cant figure out what I have done differently.

here is a code example
use Filament\Forms\Get;

Select::make('selection')
                    ->relationship('selection', 'tag',)
                    ->preload()
                    ->searchable()
                    ->columnSpan(2),
                TextInput::make('text_input')
                    ->hint(function (Get $get) {
                        return $get($selection) ? '' : 'no selection';
                    })
                    ->maxLength(255)
                    ->columnSpan(2),


For some reason the hint is not changing when an option is selected.
Solution
So I have managed to fix this by adding live() to the select. But what I don't understand is how is it working in my other app without live()
