❔ Property Changed

Hello there, i'm currently developing an app in wpf using the model mvvm and i do not understand why my datagrid won't refresh when i call : OnPropertyChanged(nameof(Thicknesses))OnPropertyChanged(nameof(Thicknesses))
to specify, i've set my datagrid to
ItemsSource="{Binding Thicknesses, UpdateSourceTrigger=PropertyChanged}"ItemsSource="{Binding Thicknesses, UpdateSourceTrigger=PropertyChanged}"
and the List ThicknessesThicknesses is supposed to be refreshed by 2 things :

• the first one is when i change the MaterialMaterial which each one contains a list of thicknesses
• the second on is when i add a new thickness
  OnPropertyChanged(nameof(Thicknesses))OnPropertyChanged(nameof(Thicknesses)) is well triggered when one of the 2 case i mentioned is filled but the update seem to works only if change the MaterialMaterial but not when i add a new thickness to it.
