closing select2 on click away when closeonselect is false

问题

is there a better way to close select2 when you click away? I have it closing with

$(document).click(function(event) { 
    if(!$(event.target).hasClass("select2-selection__rendered") &&
       !$(event.target).hasClass("select2-results__option")) {
        $("#e1").select2('close');
    }        
});

but that seems weird.

here is the fiddle http://jsfiddle.net/jEADR/5557/
