You can do two ways,

1.. Using HTML, add onchange event inline

<input type="file" id="file_select" name="file_select" value="" onchange="alert('File selected')" />

Demo: http://jsfiddle/CS3xJ/1/

2.. Using JS,

  choicefile.onchange = function(){
     alert('File selected')
  }

Demo: http://jsfiddle/CS3xJ/2/

There is actually a difference between setAttribute and attachEvent. Here is an example using attachEvent (for IE) and addEventListener (standards) to add the event.

Also, not that the event handler is a function, rather than a string:

var eventHandler = function () {
    alert("Test");
}

if (choicefile.addEventListener) {
  choicefile.addEventListener('change', eventHandler , false);
} else if (choicefile.attachEvent)  {
  choicefile.attachEvent('onchange', eventHandler );
}

Try with this:

choicefile.onchange = function() {alert("test");};

Your code seems correct. Something particular with IE is, if you put higher security level, you need to allow scripts and activeX content when you load the website.

try onclick="javascript:alert('test');" instead of onchange. Old ie versions and patibility modes don't support onchange very well.
