iCheck undo check

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?

The solution and possible the ONLY solution is to uncheck the checkbox AFTER event ended, using setTimeOut(fn,0)

$("#Lve_InclWE").on('ifChecked', function(event){
    if(!validation()){
        setTimeout(function(){
            $('#Lve_InclWE').iCheck('uncheck');
        },0);
    }
});

The reason is because the checkbox always set to checked state after the triggered event.

If you have another solution feel free to comment.
