Looking for item on the ground with model data

Im trying to make a command that looks for an item on the ground with a specific custom_model_data I have this command: /execute if entity @e[type=item,nbt={components:{"minecraft:custom_model_data":1}}] If I run it it says "test failed" even though there is an item on the floot with cmd of 1. How can I go about finding the item on the floor?
