title: How to show ngx-bootstrap datepicker when manually triggering focus on input?
body: <p>I want to implement some logic when datepicker looses focus => so (blur) but! when i want to select some date from said picker it'll trigger the logic -> closing the datepicker and not registering any value change.
  My approach is <code>(onHidden)</code> since it's not triggered when i use the datepicker but when i click outside,
  but it only fires when the datepicker is shown.</p>
  
  <p>How can I achieve to show the datepicker when i manually set the input field to focus?
  Since there are no available services and/or directive types where i can trigger <code>.show()</code>.</p>
