I did the following JQuery which didn't work:

$('#example-optionClass').val('1').prop('checked', flase);
$('#example-optionClass').val('4').prop('checked', flase);
$('#example-optionClass').val('2').prop('checked', true);
$('#example-optionClass').val('6').prop('checked', true);

Answer Source

In MultiSelect to select options you need to use

$('#example-optionClass').multiselect('select', ['2', '6']);

This is saying select the options '2' and '6' from example-optionClass.

And to unselect options you need to use

$('#example-optionClass').multiselect('deselect', ['1', '4']);

This is saying unselect the options '1' and '4' from example-optionClass

If you go to The Methods you will see all the JavaScript methods available to you, it explains how to use the 2 above functions in more detail.

Hope this helps
