I've a kendo dropdownlist which displays a primary location. I want the dropdown to set to this primary location as the default location when I click on reset.

I'm using this:

```
$("#dropDownList").val(20);
$("#dropDownList").trigger("change");

```

It's internally changing the value, but the display text does not change.

I tried the following options but nothing seems to be changing the default text:

```
$('#dropDownList option[Value=20]').attr('selected', 'selected');
$('select#dropDownList').val('20');

```
