alert when new item is loaded in grouplist

how can i define an alert when new item is added in json and UIscreen is refreshed with new item loaded

You can use events of component to assign custom action handlers

$$("mylist").attachEvent("onXLE", function(){ //on data loading alert("some message"); }) … fterrender … ader_onxle

can i play a sound when an item is clicked

You can use onItemClick event to handle item click:

$$("mylist").attachEvent("onItemClick ", function(){ //your code here })
