Repeater Checkboxes: How to Call a Method When Checked?

I have a Repeater control that has a list of strings as a datasource. Each string is in a row along with a checkbox. What is needed to make a checked checkbox call a method? Right now, I am using OnCheckedChange, as seen below.

<asp:Repeater ID="rptDiffReport" runat="server"  >
            <HeaderTemplate>
            </HeaderTemplate>
            <ItemTemplate>
                <div style="clear: both; text-align: left; margin: 10px" 
                runat="server" Visible="<%# (Container.ItemIndex+1) == 0 %>">
                </div>
                 <%# Container.DataItem %>
                 <asp:CheckBox ID="chkRow" runat="server" 
                 OnCheckedChange="rptSelectRow" Checked="false" 
                 AutoPostBack="true" CssClass="checkbox"  />
                    <br />
                    <hr />
             </ItemTemplate>
             ...
