Button Onclick event within a Repeater?

I think this is pretty easy, but I just can't seem to get it to work.

What I want to do is have the onclick fire off the function that I created for it.

------------------ASP.Net Page------------------------------
    <asp:Repeater ID="Repeater1" runat="server">
        <ItemTemplate>
            <asp:Button ID="btnProduct" runat="server" Text='<%#  DataBinder.Eval(Container.DataItem, "Products")%>' OnClick='SelectProduct(<%#  DataBinder.Eval(Container.DataItem, "ProductID")%>)' />
        </ItemTemplate>
    </asp:Repeater>
 
 
 
------------------------Code--------------------------------
    protected void SelectProduct(int ProductID)
    {
        AnswerMainDTO AuditAnswer = (AnswerMainDTO)Session["AuditAnswer"]; 
        AuditAnswer.Product = ProductID;
        Session["AuditAnswer"] = AuditAnswer;
        Response.Redirect("~/AuditMain.aspx");
    }
