dictionary - How to update map values in Go

Question

I want to build a map with string key and struct value with which I'm able to update struct value in the map identified by map key.

I've tried this and this which doesn't give me desired output.

What I really want is this:

Received ID: D1 Value: V1
Received ID: D2 Value: V2
Received ID: D3 Value: V3
Received ID: D4 Value: V4
Received ID: D5 Value: V5

Data key: D1 Value: UpdatedData for D1
Data key: D2 Value: UpdatedData for D2
Data key: D3 Value: UpdatedData for D3
Data key: D4 Value: UpdatedData for D4
Data key: D5 Value: UpdatedData for D5

Data key: D1 Value: UpdatedData for D1
Data key: D2 Value: UpdatedData for D2
Data key: D3 Value: UpdatedData for D3
Data key: D4 Value: UpdatedData for D4
Data key: D5 Value: UpdatedData for D5
