javascript - replace the submit button -

i tried implement file upload process in grid.
chose use jquery.iframe-post-form plugin.
solutions post data of form , after upload file.
in order post data of form @ once (lastname, ...) + photo, replaced submit button of form (sdata) mine.

$(formid).removeattr('onsubmit'); $(formid).iframepostform({ ... });  

i attached code new button (click event). changed submit button id , jqgrid not attach click event .

$('#sdata').attr('id', 'mysubmit')                           .click(function(e)            {               ...              $(formid).submit();            }) 

therefore changed behaviour of jqgrid: no beforesubmit event, no aftersubmit event, no aftercomplete event !

how fire after aftersubmit event getting errors ?

how overriding default behavior of button? custom stuff submit form?

$(document).ready(function () {      $(":button").click(function (event) {                  event.preventdefault();                  //do stuff submit form                 $('form').submit();               }); });
