[go-nuts] troubles with stderr

I am trying to print stdout and stderr of my test script in golang app
(sample.go) : ./test.sh | ./sample
test
#!/bin/bash
echo $$
i=0

while [ $i -lt 50 ]
do
     echo "$i time HELLO STDIN, $$!!!"
     echo "$i time HELLO STDERR, $$!!!" >&2
     sleep 1
     i=`expr $i + 1`
done

-------------------------
sample.go
------------------------
package main
import (
          "bufio"
          "fmt"
          "os"
         "os/signal"
  )


func main() {
         c := make(chan os.Signal, 1)
         signal.Notify(c, os.Interrupt)
         go func(){
                 for sig := range c {
         // sig is a ^C, handle it
                 fmt.Println(sig)
                 os.Exit(0)
            }
         }()
         consolereader := bufio.NewReader(os.Stdin)
         erreader := bufio.NewReader(os.Stderr)
         for {
                 input, err := consolereader.ReadString('\n')

                 if err != nil {
                         fmt.Println(err)
                         os.Exit(1)
                 }

                 errinput, err1 := erreader.ReadString('\n')
                 if err1 != nil {
                         fmt.Println(err1)
                         os.Exit(1)
                 }

                 fmt.Println(input)
                 fmt.Println(errinput)
                 //fmt.Println(err)
         }
         fmt.Println("\"reader finished\"");
}
I expected output to be like this
0 time HELLO STDOUT, 1077!!!
0 time HELLO STDERR, 1077!!!
....

But i see only STDERR:
0 time HELLO STDERR, 1077!!!
1 time HELLO STDERR, 1077!!!
Any idea what i do wrong in my code? Are there any examples on this
particular task?
Thank you,
