Language Binding does not update when value of binded property changes

[DineshSolanki]

Describe the bug I have used the following way to bind my label

<Label BorderThickness="0" Content="{ex:Lang Key={Binding AppStatus}}"/>

I have the following keys in my Lang.resx = "Idle", "Searching" whose values are also defined. Now the Initial value of AppStatus is set to "Idle" and it shows and changes as I change language, but when I change the value of AppStatus to something else, say AppStatus = "Searching" I expected the value on the UI to change as well(to display the localized value of 'Searching'), but it stays on "Idle".

To Reproduce Steps to reproduce the behavior:

1. Bind any control with {ex:Lang Key={Binding BindingProperty}}
2. Change the value of 'BindingProperty' to something else from the code
3. The display value of the control doesn't change.

Expected behavior When the value of BindedProperty is changed, I expected it would display the localized string of new value.

Environment (please complete the following information):

• .net: 5.0
• IDE vs2019
• Version 3.3.7
