Bindable Property In Custom Control

I have created a custom control that inherits from the Panel control. I did this to add a click event to it. The custom control is contained inside a ListView so I am trying to add a property that I can bind data to and retrieve on the click event.

Here is the markup:

<asp:ListView ID="lstvwCalendar" runat="server" OnLayoutCreated="lstvwCalendar_LayoutCreated">
     <layouttemplate>
                    <table>
                        <tr class="day_of_week">
                            <th>
                                Name
                            </th>
                        </tr>
                        <asp:PlaceHolder ID="itemPlaceHolder" runat="server">
                    </table>
                </layouttemplate>
                <itemtemplate>
                    <tr class="day_of_week">
                        <td>
                            <cc1:clickablepanel id="pnlSunday"  runat="server"  önclick="ClickablePanel1_Click"
                                width="100%" height="100%" CommandArgument='<%# Eval("Name") %>'>
                            
                        </td>
                    </tr>
                </itemtemplate>

The problem is that the CommandArgument property is always null.

Here is the code for the custom control:

public class ClickablePanel : System.Web.UI.WebControls.Panel, System.Web.UI.IPostBackEventHandler
    {
        [System.ComponentModel.Bindable(true)]
        public string CommandArgument { get; set; }
        public ClickablePanel() : base()
        {
            
        }
        private event EventHandler _click;
        public event EventHandler Click
        {
            add { _click += value; }
            remove { _click -= value; }
        }
        
        protected virtual void FireClickEvent()
        {
            if (_click != null)
            {
                _click(this, new EventArgs());
            }
        }
        protected override void AddAttributesToRender(HtmlTextWriter writer)
        {
            writer.AddAttribute(HtmlTextWriterAttribute.Onclick, Page.ClientScript.GetPostBackEventReference(this, String.Empty));
            base.AddAttributesToRender(writer);
        }
        public void RaisePostBackEvent(string eventArgument)
        {
            FireClickEvent();
        }
        public event System.ComponentModel.PropertyChangedEventHandler CommandArgumentChanged;
        public void OnCommandArgumentChanged(System.ComponentModel.PropertyChangedEventArgs e)
        {
            if (CommandArgument != null)
            {
                CommandArgumentChanged(this, e);
            }
        }
    }

Any help would be great. Thanks.
