CreateLinkButton should be called during init of your page, on each postback.
So the OnInit event should look like this

protected override void OnInit(EventArgs e)
{
base.OnInit(e);
CreateLinkButton();

}

This is how you add an eventhandler to the button:

linkButton.Click += new EventHandler(this.linktest_Click);
