        var inputTextId = $('#' + this.id);
        var inputText = inputTextId.val();

        var errorFor = this.id;
        if (!isValidChar(inputText)) {
            $('#' + this.id).val('').valid();       
            setTimeout(function () { replaceErrorMsg(errorFor); }, 100);
        }
    }); 
});
