I`m using Kakao map api and infowindow.

I want to use my custom onClick function in backtick string.

But same error repeated (Unexpected end of input.)

Here`s my code.

kakao.maps.event.addListener(markeenter code herer, 'click', function () {
        function aa() {
          console.log('12123');
        }
        infowindow.setContent(
          `<div style="padding:5px;font-size:12px;">
            <div style="display:flex;">
              <div>${place.place_name}</div>
              <button onClick=" +
            aa +
            ">추가</button>
            </div>
            <div>
              <div>
                ${place.road_address_name}
              </div>
              <div>
                ${place.address_name}
              </div>
              <div>
                ${place.phone}
              </div>
            </div>
          </div>`,
        );
        infowindow.open(map, marker);
      });
