Need help in adding additional command in VSPackage.cs

i am currently facing an issue, and desperately need help. any help will be very much appreciated.

in my vsct file, i do have 2 buttons. 

   <Button guid="guidMyFyp_PluginCmdSet" id="cmdidGenerateDiagram" priority="0x0100" type="Button">
        <Parent guid="guidMyFyp_PluginCmdSet" id="MyMenuGroup" />
        <Icon guid="guidImages" id="bmpPic1" />
        <Strings>
          <ButtonText>Generate Diagram</ButtonText>
        </Strings>
      </Button>

      <Button guid="guidMyFyp_PluginCmdSet" id="cmdidCreateRulesCommand" priority="0x0200" type="Button">
        <Parent guid="guidMyFyp_PluginCmdSet" id="RulesGroup" />
        <Icon guid="guidImages" id="bmpPic2" />
        <Strings>
          <CommandName>cmdidCreateRulesCommand</CommandName>
          <ButtonText>Create Rules</ButtonText>
        </Strings>
      </Button>

and i am trying to create a new command for the button with the id "cmdidCreateRulesCommand". therefore in my VSPackage.cs, i included the following in my initialize method.

  OleMenuCommandService mcs2 = GetService(typeof(IMenuCommandService)) as OleMenuCommandService;
            if (null != mcs2)
            {
          
                CommandID openRuleForm = new CommandID(GuidList.guidMyFyp_PluginCmdSet,(int)PkgCmdIDList.cmdidCreateRulesCommand);
                MenuCommand menuItem2 = new MenuCommand(MenuItemCallback, openRuleForm);
                mcs2.AddCommand(menuItem2);
            }

however upon running my program, it is not able to detect my new command to execute my method. can anyone please enlighten me?
