Custom Button exposed property on details panel

I’m very new to UE4 so please excuse me if this is a silly question.

I’m attempting to make a custom text-button. I’ve bound the text to a variable and made the variable editable and available at spawn. In another widget designer I drag the text-button to the screen and see the exposed text property in the details panel. However, when I try to change the value it doesn’t update in the viewport.

In context, I’m trying to create a simple word puzzle and want to create a panel showing all available consonants. So I wanted to have each consonant be a text-button. I know I can do this in blueprint on construction but I’d like to be able to visualize it in the editor.

Thanks.

I’ve also noticed that when I run the game the value of the text I set for the value shows correctly. So my issue is getting the text value change to display in the editor.
