go - Stop goroutine execution on timeout

Question

I want to stop goroutine execution on timeout. But it seems like it is not working for me. I am using iris framework.

  type Response struct {
    data   interface{}
    status bool
  }

  func (s *CicService) Find() (interface{}, bool) {

    ch := make(chan Response, 1)

    go func() {
      time.Sleep(10 * time.Second)

      fmt.Println("test")
      fmt.Println("test1")

      ch <- Response{data: "data", status: true}
    }()

    select {
    case <-ch:
      fmt.Println("Read from ch")
      res := <-ch
      return res.data, res.status
    case <-time.After(50 * time.Millisecond):
      return "Timed out", false
    }

  }

Output:

 Timed out
 test
 test1

Expected Output:

 Timed out

Can somebody point out what is missing here? It does timeout but still runs goroutine to print test and test1. I just want to stop the execution of goroutine as soon as there is timeout.
