Input event triggered on Internet Explorer when placeholder changed

Question

As it is shown in this jsfiddle example when i change placeholder it triggers input event. I tested it on I.E 11 version but i guess that older versions have same problem. The other browsers does not behave like this. Is this I.E bug ? If so what is workaround for this problem on I.E ?

Here is html markup.

<input type="text" />
<button>Change PlaceHolder</button>

And here is javascript part.

var i = 0;
$('button').click(function(){
  $('input').attr('placeholder','placeholder ' + i++);
});

$('input').bind('input',function(){
    alert('input even occur');
});

Answer 1

checking if input is focused should be enough

$('input').bind('input',function(){
    if($(document.activeElement) != $('input'))
        return;
    alert('input even occur');
});

this also "fixes" the input event being triggered without any actions when placeholder contains an accented character
