Changing choices of a checkbox/ radio question programmatically by surveyModel should chnage choices of all the question with selected name, not the first occurence only

// In JS:
// we have 2 different questions with same name but different titles in different panels, 
// on changing 2nd question we execute following line
surveyModel.getQuestionByName("column").choices = ["s1","s2","s3"];
// above line does change the choices of the first title with name column but 2nd title with name column does not get the new choices.
