How to change the text in the balloon on the click of a button in Yandex map?

Question

Yandex maps

There are 10 markers. Clicking opens a balloon with text and a change button.
On clicking the button, the text changes to a shape and the balloon becomes draggable.
I change the text, I transfer the balloon, I press save.
How to do this?
On Google it's elementary with jquery, but there are big problems with Yandex.
Maybe an example or something like that? Thank you.

/**
             * Добавляем метку и всплывающее окно
             */
      
             var myPlacemark = new ymaps.Placemark(coords, {
       
             balloonContent: desc_html
             }, {
            iconLayout: 'default#image',
       /*iconImageHref: 'myIcon.gif',
       iconImageSize: [30, 42],
       iconImageOffset: [-3, -42],*/
       iconImageHref: 'cryplat.gif',
       iconImageSize: [72, 36],
       iconImageOffset: [-36, -30]
             });

             myMap.geoObjects.add(myPlacemark);
