I want to show modal in some cases. And handle event like "close modal". 
I implement it like in documentation. 

let thisClass = this, 
   width = '400px', 
   height = '620px', 
   option = { 
        location: 'modal', 
        size: { 
        width: width, 
        height: height 
       } 
    };

thisClass.clientZendesk = ZAFClient.init();
thisClass.clientZendesk.invoke('instances.create', option).then(function(modalContext) {
    
    let instanceGuid = modalContext['instances.create'][0].instanceGuid, 
        modalClient = thisClass.clientZendesk.instance(instanceGuid);
    
    modalClient.on('modal.close', function() { 
        console.log("CLOSED modal")
    });
}); 

But console.log did not work. Did not execute callback for event 'modal.close'

modalClient.on('modal.close', function() {
    SOME_FUNCTION()
});

what wrong?
