Dynamically created asp linkbutton to call c# function

I have the following code which generates a list of linkbuttons:
 

public void getSocialStories()
    {
        string user = getSelectedUser();
        List<SocialStory> stories = new List<SocialStory>();
        stories = functions.getSocialStories(user);
 
        foreach (SocialStory story in stories)
        {
            LinkButton lb = new LinkButton();
            lb.Text = story.Social_story_name;
            ph.Controls.Add(new LiteralControl("<br />"));
            ph.Controls.Add(lb);
        }
    }

 
And I have a empty asp panelholder:
 

<asp:PlaceHolder runat="server" ID="ph"></asp:PlaceHolder>

 
It gets filled with the linkbuttons, which are a result from a mssql database.
 
I want when a linkbutton is clicked to call a c# function. This function should take a parameter the social_story_id. How can I do that ?
 
I think one of the ways is using Ajax, but I don't know how to do it. Are there other ways and if not how to do it with ajax?
