Same code I'm using of dojo documentation just downloaded code work fine but onchange event do not fire on my project. I have make it to work by firing onblur onBlur: function(){alert(3)} What thing may cause onchange event not fire? var filteringSelect = new FilteringSelect({ id: "stateSelect", name: "state", value: "CA", store: stateStore, searchAttr: "name", onChange: function(){alert(3)} }, "stateSelect");
