Confirmation dialog Box does not file itemCommand in asp.net

Question

I am using asp.net 4.5 with c#.From repeater on delete command I want to show confirmation dialog box.If user Press "Yes" than delete that record.My delete logic is in "rep_ItemCommand" event.Here Is my Code

    <as:Pager ID="pgeImportedFiles" AutoPostBack="True" EnableViewState="true" runat="server" RepeaterControlID="rptImportFiledata" Visible="false" PageSize="10" DisplayPagerOption="Top">
        <RepeaterTemplate>
            <asp:Repeater ID="rptdata" EnableViewState="true" runat="server" OnItemCommand="rptdata_ItemCommand" >
                <ItemTemplate>                            
                        <div >
                            <asp:LinkButton ID="lbnDelete"   
                                OnClientClick="javascript:return showConfirmation('Are you sure You want to Delete this File?',this.id);"                                         
                                runat="server" CommandName="Delete" CssClass="EditBtn" CommandArgument='<%# Eval("ID") %>'>Delete</asp:LinkButton>
                        </div>    
                </ItemTemplate>
            </asp:Repeater>
        </RepeaterTemplate>
    </as:Pager>

 protected void rptdata_ItemCommand(object source, RepeaterCommandEventArgs e)
 {   
   //logic for deleteing
 }

this javascript in js file and "divDialogMessage1" and "divAlertBox1" defined in this file

    $(divDialogMessage1).html(confirmationMessage,uniqueID){
     var result = false;
        $(divAlertBox1).dialog({
            title: "Confirmation",
            buttons: {
                "Yes": function () {
                    __doPostBack(uniqueID);
                    $(this).dialog("close");
                },
                "No": function () {
                    $(this).dialog("close");
                }
            }
        });
        $(divAlertBox1).dialog('open');
        return result;}

By this dialog is display on click on delete link and page also post back if select "yes" option.But rptdata_ItemCommand not firing.

Any solution for this?

Logic for deleting

protected void rptdata_ItemCommand(object source, RepeaterCommandEventArgs e)
 {   
   //logic for deleteing
    switch (e.CommandName)
            {
                case "edit":
                    MyEditFunction(e.CommandArgument.ToString());
                    break;
                case "delete":
                    MyDeleteFunction(Convert.ToInt32(e.CommandArgument));
                    break;
            }
 }

Confirmation Message

Add OnItemDataBound="AddDeleteConfirmation" to your repeater mark up and the following code in the code behind

protected void AddDeleteConfirmation(Object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType != ListItemType.Header && e.Item.ItemType != ListItemType.Footer)
            {
                // adds a confirmation javascript to ensure that deleting the template is really what the user wants.
                ((LinkButton)e.Item.FindControl("lbnDelete")).Attributes["onclick"] = "javascript: return confirm('Are you sure you want to delete this record?')";
            }
        }

If I use simple java-script Confirmation Box My code is also working. But I am creating a custom Confirmation Box with different style and UI. For that by dialog Box return true or false can't return after press "Yes" or "No"

And By postBack event repeater ItemCommand not called. Only page Load event calling.
