javascript - detect when user check or uncheck row on client side in primefaces datatable -

-

i use this row editing primefaces datatable , added multiple selection feature through this example

then want detect on client side when user check or uncheck 1 row , number of rows checked @ each change

i tried many ways firebug .... no result

here 1 of essays (just testing): 

$(function(){                                        $('.ui-chkbox-box.ui-widget.ui-corner-all.ui-state-default').mousemove(function(){                      if(('.ui-chkbox-box.ui-widget.ui-corner-all.ui-state-default').hasclass('ui-state-active'))                         alert('show');                 });

do have idea

if want know when user clicked checkbox located in datatable, can use code listen click , verify if checked or not:

jquery(".ui-chkbox").click(function () {     if(jquery(this).find("span").first().hasclass("ui-icon-check"))         alert("unchecked");                 else         alert("checked"); }

notice if clause inverted, happens because function called before primefaces adds class "ui-icon-check" div.
