I want to style my website forms, inputs and selects. I used [Bootstrap](http://getbootstrap.com/) for the inputs and [**Bootstrap-select**](http://silviomoreto.github.io/bootstrap-select/) for selects and [**iCheck**](http://damirfoy.com/iCheck/) for checkboxes. The problem is that iCheck does not work correctly with Bootstrap-select.

Here is jsFiddle test: <http://jsfiddle.net/36Xpf/>

Now, try to check the iCheck checkbox, the select of bootstrap-select will not be disabled. Then check the standard square checkbox, the select of bootstrap will be disabled.

I get the attribute disalbled to select if a checkbox is checked usign jQuery `.change()`:

```
$('#checkbox1').change(function(){
  if (this.checked) {
    $('.selectpicker').attr('disabled', false);
  } else {
    $('.selectpicker').attr('disabled', true);
  }                   
});

```

What did I do wrong? Why the disabled attribute doesn't work on bootstrap select?  

Any help is appreciated! Thank you!
