Assigning value to input field on nested:fieldAdded

Question

I have an upload file field. On change of this field, I am triggering add nested field and on 'nested:fieldAdded' I am trying to assign the value to the input file field given in the new generated nested form by using the following jquery:

$(document).off('change').on('change', '#add_gallery_image, #add_place_image',function () {
      if (typeof (FileReader) != "undefined") {
        var reader = new FileReader();
        var file = $(this)[0].files[0];

        file_selector_id = $(this)[0].id;
        var reader = new FileReader();
        var association = ''

        if (file_selector_id.includes("add_gallery_image")) {
            association = 'tribute_galleries'
            limit_count = GALLERY_LIMIT_JS
        } else {
            association = 'tribute_places'
            limit_count = PLACES_LIMIT_JS
        }
        
        reader.onload = function (e) {
            file_src = e.target.result;            
            $(".add_nested_fields[data-association='" + association + "']").click();
        }
         reader.readAsDataURL($(this)[0].files[0]);
        // reader.readAsDataURL($(this)[0].files[0]);
    }
    })

$(document).on('nested:fieldAdded', function(event){
  if(file_selector_id!="") {
    var field = event.field;
    var dateField = field.find('.add_image');
    dateField[0].files = $('#' + file_selector_id)[0].files;
  }
})

<div class="upload-btn position-relative">

        </div>
      </div>
    </div>

Also, the above code is working fine for chrome but in firefox, it is assigning the last uploaded file value to all the newly generated nested forms along with the current generated nested form.
