Why is the list not being filtered?

Question

JavaScript

Hello!
I'm going through the ember tutorial and subvising at this stage https://guides.emberjs.com/v2.7.0/tutorial/autocom...
Items in the list are not filtered according to updated according to the data entered. Copy-pastil seems to be all one to one.

In the console, I see that the backend is filtering the data in accordance with the request, but the list on the page is not updated. There are no errors either in the ember cli or in the console. What can be wrong?
