Problem Grid with my filter date column

I have a problem with my date column of the grid with filter.
If I enter 2 digits example 09 I have my dates ex. 18/10/2009, on the other hand if I enter 2009 in my column filter date=> I no longer see any result.
I saw that my DataProvider.fromFilteringCallbacks is not called.
Do you know why it works with 2 digits and not with 4?
