Align button horizontally with text in a radio select list


I’m working on a ionic page that allows users to select the language they prefer. A radio selection list is used to list all the languages, and at the right of each item, a button is shown if that item is selected. The problem is that the button is not align horizontally with the radio text. Here is the codepen link

As you can see, the button sits on the bottom line, while the radio text is in the middle of a row. I’d like to move the button up in the middle as well. Could not figure out how to do it. Can anyone help?
