dynamic searchbar symfony 6.2

Hello everyone,
The thing that I want to do is a dynamic searchbar in symfony with ajax.
I already have a filter system and i want the searchbar work with it.
I’m trying to do that in ajax + symfony 6.2.
My PHP version is 8.1.10.
the code in my controller est*: https://sharemycode.io/c/f4341e6
the code in my twig est*: https://sharemycode.io/c/879139d
the code in my js*: https://sharemycode.io/c/1615e4d
the code in my form: https://sharemycode.io/c/aa9a8d0
forthe Repo*: https://sharemycode.io/c/d29c882
The probleme here is that the search don’t refresh when i write in the input (nothing happen).
Maybe the problem is from the javascript ?
Thanks for reading and for ur help !

I tried to vardump the result in controller, i have it but this is only when i send the form searchbar ..
