[Vuejs]-Vuejs Array update with new value not working as expected

Your code shows you’re not using result from this.GET_SURVEY_QUESTION() to update anything. By the way, I don’t have enough SO reputation to add comments to address the other commenter, but your array is reactive. Modifying array items or object properties are both reactive operations. If you were adding or removing items/properties then it would not be reactive but I don’t see you doing that here (setting an entirely new array is fine).
