BSMultiSelect changing selected items through Javascript/Jquery

I've been using this custom Bootstrap select plugin BSMultiselect. I need to select some options after the page has already been loaded, using jQuery/Javascript.

The API documentation is not very clear how to do this. What I've tried is:

var bsMultiSelect = $('#facilityFilter').BsMultiSelect();
bsMultiSelect.updateOptionSelected(0);

This effectively does nothing.

In order to select an option you need for the first set the selected attribute before you update the bsMultiSelect.

The snippet:

$(function () {

  var $multiSelects = $("select[multiple='multiple']");
  $multiSelects.bsMultiSelect();

  // set the selected attribute...
  $multiSelects.find('option').eq(0).prop('selected', 'selected');

  // ....so, update the bsMultiSelect
  $multiSelects.data('DashboardCode.BsMultiSelect').updateOptionSelected(0);

});
.row {
    background: #f8f9fa;
    margin-top: 20px;
}

.col {
    border: solid 1px #6c757d;
    padding: 10px;
}
