Change event for a date time field does not work when used in a multi field

Hi All,

I have a multi field which contains a number of fields out of which one is a datetime field which is declared as below

this.dateField = new CQ.Ext.form.DateField({
                width: 300,
                allowBlank: false,
                hideTime:true,
                listeners: {
                    change: {
                        scope:this,
                        fn:this.updateHidden
                    },
                    dialogclose: {
                    scope: this,
                    fn: this.updateHidden
                }
                }
            });

The field renders correctly, however when I try to change the date, the date change does not happen and it retrieves the old date value. This is only happening when I am using the date field. Am I missing something here?

Thanks,

Ravi
