I create CheckGroup and add items. When I click scroll down, items doesn't scroll, why ?

#include <Controls\CheckGroup.mqh>
CCheckGroup MyCheckGroup;

int OnInit()
  {
   MyCheckGroup.Create(0, "MyCG", 0, 40, 40, 200, 150);
   MyCheckGroup.AddItem("Item 1", 0);
   MyCheckGroup.AddItem("Item 2", 0);
   MyCheckGroup.AddItem("Item 3", 0);
   MyCheckGroup.AddItem("Item 4", 0);
   MyCheckGroup.AddItem("Item 5", 0);
   MyCheckGroup.AddItem("Item 6", 0);
   MyCheckGroup.AddItem("Item 7", 0);
   MyCheckGroup.AddItem("Item 8", 0);
   
   return(INIT_SUCCEEDED);
  }

int OnCalculate(const int rates_total,
                const int prev_calculated,
                const datetime &time[],
                const double &open[],
                const double &high[],
                const double &low[],
                const double &close[],
                const long &tick_volume[],
                const long &volume[],
                const int &spread[])
  {

   return(rates_total);
  }

void OnChartEvent(const int id,
                  const long &lparam,
                  const double &dparam,
                  const string &sparam)
  {
    MyCheckGroup.OnEvent(id,lparam,dparam,sparam);
  }
