I want to do some validation when checkbox is checked and uncheck it if validation fails.

Right now, the checked property is false but the checkbox remains checked.

Mycode:   

```
$("#Lve_InclWE").on('ifChecked', function(event){
    some_function();
    if(!some_validation())
        $('#Lve_InclWE').iCheck('uncheck');
});

```

HTML:   

```
<div class="icheckbox_flat-green checked" style="position: relative;">
<input type="checkbox" class="icheck" id="Lve_InclWE" name="Lve_InclWE" style="position: absolute; opacity: 0;">

```

update1: Even if I do this, the problem remains:   

```
$("#Lve_InclWE").removeProp("checked"); 
//$("#Lve_InclWE").prop("checked",false);
$("#Lve_InclWE").iCheck('update');

```

update2: Tried removing checked class at parent div but the same. Is it because I execute within the check event? 

```
$('#Lve_InclWE').closest("div").removeClass("checked");

```

**update3:** I added an alert at the end of the "ifChecked" event and noticed that the checkbox actually been unchecked, but it returns to checked state after the event ends. Which means I cannot perform the undo check(uncheck) within the triggered event, any method you can think of?
