mfc changing checkbox in a view background color not work

I wanted to change the background color of the check box, so I made the following class.

// custom_button.h
#pragma once


class CCustomButton : public CButton
{
    DECLARE_DYNAMIC(CCustomButton)

public:
    CBrush brush_ = RGB(0, 255, 0);

protected:
    DECLARE_MESSAGE_MAP()
    afx_msg HBRUSH CtlColor(CDC* /*pDC*/, UINT /*nCtlColor*/);
};

// custom_button.cpp
#include "pch.h"
#include "custom_button.h"


IMPLEMENT_DYNAMIC(CCustomButton, CButton)


BEGIN_MESSAGE_MAP(CCustomButton, CButton)
    ON_WM_CTLCOLOR_REFLECT()
END_MESSAGE_MAP()


HBRUSH CCustomButton::CtlColor(CDC* pDC, UINT /*nCtlColor*/)
{
    return brush_;
}

When this control is put into the dialog, it works fine, but when it is put into the view, it does not work even though the CCustomButton::CtlColor is called.

void CTestAppView::OnInitialUpdate()
{
    CFormView::OnInitialUpdate();
    GetParentFrame()->RecalcLayout();
    ResizeParentToFit();

    button.Create(_T("Test"), WS_CHILD | WS_VISIBLE | WS_BORDER | BS_AUTOCHECKBOX, CRect(10, 10, 70, 60), this, IDC_STATIC);
}

BOOL CTestDlg::OnInitDialog()
{
    CDialogEx::OnInitDialog();

    button.Create(_T("Test"), WS_CHILD | WS_VISIBLE | WS_BORDER | BS_AUTOCHECKBOX, CRect(10, 10, 70, 60), this, IDC_STATIC);

    return TRUE;
}

Why are the results different?
