JQuery multiselect selectedText does not work with JQuery > 1.4.2 when select list contains only one element

This is the problem with the change in the jquery version. Previous jquery(up to 1.4.2) the checkbox checked can be found by using "[checked]". Later versions of jquery changed to ":checked". To fix this issue go the jquery multiselect plugin js file line number 206 and change  $checked = $inputs.filter('[checked]') to $checked = $inputs.filter(':checked'). This solution works for me.
