Expected behavior

For a datepicker with the option editable: true

1. When I click on the inputfield I should be able to change the date by typing
2. When clicked on an icon the datepicker pop-up should be opened with a Jquery call

Actual behavior

Modification by typing works, but when I try to open the picker with Jquery nothing happens. I have to click multiple times to open the datepicker

Resources (screenshots, code snippets etc.)

instantiate:

Jquery function to open the picker:

I found the inspiration for the Jquery function in an old forumpost, the new website does not contain a Jquery-section for datepicker.

Any idea how I can resolve this problem?

function activatePicker(pickerId){
    var picker = $(`#${pickerId}`).pickadate('picker');
    event.stopPropagation();
    event.preventDefault();
    picker.open();
    picker.open();
    picker.open();
}
