Description

Hi, in the example Custom validators,
(https://github.com/gin-gonic/examples/blob/3a0d22aa344fcf014612f43f5bf21f9c9997fd67/custom-validation/server.go#L32)
v, ok := binding.Validator.Engine().(*validator.Validate) returns v=nil and ok=false on my machine. Therefore the validator bookableDate would not be registered.

Environment:
Windows 10
Go 1.13
github.com/gin-gonic/gin v1.5.0
github.com/go-playground/validator/v10 v10.2.0

Research direction

Start with custom-validation/server.go around line 32 and reproduce the example using the reported Go, Gin, and validator versions. Check why binding.Validator.Engine() does not return the expected validator and verify that bookableDate is registered and used by the example. Done means the example runs with the custom validation enabled.
