javascript - Jquery change event not working -

i have html:

<form id="fileuploadform">     <input type="file" id="fileupload" name="fileupload" /> </form> 

and jquery:

$(':file').change(function(){     var file = this.files[0];     ... }); 

the problem is: change function fires when file selection different selection made previously. of course meaning of 'change' event. want function called file dialog closes, no matter what.

i tried using 'select' event -- never gets called

i tried:

$(':file').bind('dialogclose', function(event) {     alert('closed'); }); 

and:

$(':file').live("dialogclose", function(){     alert('closed1'); });  

they didn't work either.

try use code.

$('#fileupload').on('change', function () {     alert('hi');     //do function. }); 

this function call select different files otherwise not.
