Here is a fixed version, it updates when you let go of the mouse

I added a span to your P

const getYYYYMMDD = date => date.toISOString().split("T")[0];

on_date_change: function(task, start, end) {
  task.start = getYYYYMMDD(start);
  task.end = getYYYYMMDD(end);
  const cardEnd = document.getElementById("fEnd");
  if (cardEnd) {
    cardEnd.textContent = task.end;
  }
},

'use strict'

const getYYYYMMDD = date => date.toISOString().split("T")[0];

function getView(view) {
  gantt.change_view_mode(view);
}

let tasks = [{
    id: 'Task 1',
    name: 'Redesign website',
    start: '2022-1-28',
    end: '2022-1-31',
    progress: 20,
    dependencies: ''
  },
  {
    id: 'Task 2',
    name: 'Redesign website',
    start: '2022-2-2',
    end: '2022-2-10',
    progress: 20,
    dependencies: 'Task 1'
  },
  {
    id: 'Task 3',
    name: 'Redesign website',
    start: '2022-2-12',
    end: '2022-2-20',
    progress: 20,
    dependencies: 'Task 2'
  }
]

let gantt = new Gantt("#gantt", tasks, {
  on_click: function(task) {
    // console.log(task);
  },
  on_date_change: function(task, start, end) {
    task.start = getYYYYMMDD(start);
    task.end = getYYYYMMDD(end);
    const cardEnd = document.getElementById("fEnd");
    if (cardEnd) {
      cardEnd.textContent = task.end;
    }
  },
  on_progress_change: function(task, progress) {
    // console.log(task, progress);
  },
  on_view_change: function(mode) {
    // console.log(mode);
  },
  custom_popup_html: function(task) {
    return `
            <div class="card" style="width: 10rem;">
              <div class="card-body">
                <h6>${task.name}</h6>
                <p>Expected to finish by <span id="fEnd">${task.end}</span></p>
                <p>${task.progress}% completed!</p>
              </div>
            </div>
          `;
  }
});

let btnContainer = document.getElementById("myButtonGrp");
let btns = btnContainer.getElementsByClassName("btn");
for (let i = 0; i < btns.length; i++) {
  btns[i].addEventListener("click", () => {
    let current = document.getElementsByClassName("active");
    current[0].className = current[0].className.replace(" active", "");
    this.className += " active";
  });
}
