IE doesn't allow to upload the file, if it is not keybord click for input type=file

问题

I have a requirement where i need to trigger the input[type=file] from another button and upload the files. This input[type=file] is a popup window for browsing the file which the user wants to upload. This window opens successfully but when uploading the file, it gives me SCRIPT5: Access is Denied error . I cannot replace the fake button with input[type=file], is there a way i can trigger click on input[type=file] even it is not from keyboard click and still upload the file. As per my research IE doesn't allow upload file unless we trigger input-type=file via keyboard click.

var uploadConfig ={
    init: function(){
        $('input#fileUpld_input').livequery("click",function() {
        });
    },
    open: function() {
        $('input#fileUpld_input').trigger('click');
    },
    upload: function(){
        $('.start').click();
    }

Browser

<input type="file" id="fileUpld_input" name="fileUpld_input" class="fileUpld">

Use the code shown in the other answer worked for me: working JSFiddle

<input type="file" id="fileUpld_input" name="fileUpld_input" class="fileUpld">

I had the same problem, but determined that it was with IE not the code. After spending waaay too much time trying to sort out the error in my code; I fired up my laptop and could not replicate it. Eventually a reboot and restart of IE fixed the issue.
