Minecraft – How to make loot tables work in 1.14

I've been trying to set up a loot table for a chest. For some reason it doesn't work.
I put the .json file into "datapacks/loottables/data/minecraft/loot_tables/chests/".
There is a "pack.mcmeta" file in the correct folder right next to the data folder. The game does list this datapack when running the command /datapack list.
I named the file "buried_treasure.json".

Here is the command I used: /setblock ~ ~ ~ chest{LootTable:"minecraft:loot_tables/chests/buried_treasure.json"}
The chest comes out empty.

Here is the json file:
