New inside door handle needed

Hi there, I'm not sure what brand or model there door is, only that it came from Home Depot. The inside handle is broken. Where the arrow points to is where it pulls apart from the door and we push it back in. The part that catches on the thing on the door frame to stay closed is broken too, you see it in the photo. What part(s) do you recommend I buy to fix this? The door itself is fine it's just a few years old. Thanks.
