jquery - Chrome checkbox not changing -

i have simple checkboxes in table. checkbox tag see in code:

<input type="checkbox" id="ifact123" onchange="submit_status_change(123,$(this).prop('checked'));" > 

now example in firefox, works fine. in chrome, following happens:

• when checkbox clicked, checkbox not appear change checked/unchecked. stays same. @ least visually
• the submit_status_change() runs ok , if reload page, element loaded checked (which info database). since function takes info $(this).attr('checked')), element must checked @ least @ time parameter send - doesn't appear to.

now has idea, or experience such problem?

if think has submit function, here is:

function submit_status_change(id, val){   //$.post('something.php',{'change_status':id, 'status':val}, function(){});  } 

update: attr changed prop

chrome changes checkbox, @ least visually. onchange event doesn't seem happen.

firefox:

    typeerror: $(...).prop not function [break on error]     submit_tech_status(123,$(this).prop('checked')); 

update2: cut off code. submit function pretty clear. firefox has error prop, chrome prints no error, doesn't run submit function. different before, checkbox in chrome appeared not checked or unchecked, function went ok.

just write like:

$("#ifact123").change( function() {    var c = $(this).prop("checked");    // whatever want c value });
