Hope you found an solution already, but what I see it that you are including
erb tags in the javascript code. Change <%= %> to #{ } and I guess you
should be able to get it working:
:javascript
$('#number_of_passengers').change(function() {
var $num_of_passengers = $(this).val();
for($i=0; $i<$num_of_passengers;$i++) {
$('.passenger-info ul').append('#{
escape_javascript( render :partial => "new_passenger", :locals
{:booking => @booking }) }');
}
})
