Bash equality not behaving as I expect it

I want to check if last command failed or not in bash. I base this mini script on this

#!/bin/bash
mkdir nothere/cantcreate

echo $?

if [ $? -eq 0 ]; then
    echo "command succeed"
    else
    echo "command failed"
fi

This prints the following:

mkdir: cannot create directory ‘nothere/cantcreate’: No such file or directory

1

command succeed

I expect it to print command failed as the value of $? is 1. Why does the equality not behave as I expect ?
