MessageDialog buttons localization

[Dmitriano]

What is right way to localize MessageDialog's Yes and No buttons? I tried adding the following to my translation file, but with no success:

<context>
    <name>DefaultMessageDialog</name>
    <message>
        <source>Yes</source>
        <translation type="Да"></translation>
    </message>
    <message>
        <source>No</source>
        <translation type="Нет"></translation>
    </message>
</context>

I use QuickControls2, QT 5.13
