You could change my example to use named callbacks and it will give the same result:\r\n{code}\r\nconst win=Ti.UI.createWindow({\r\n\tbackgroundColor:'#fff'\r\n});\r\nconst view=Ti.UI.createButton({\r\n\ttitle:'This button does nothing on OS...'\r\n});\r\nview.addEventListener('click',callback1);\t\r\nview.removeEventListener('click',callback2); //This removes the callback added above, but it shouldn't!\r\nwin.add(view); \r\nwin.open();\r\nfunction callback1() {\r\n\talert('This alert does not open on iOS...')\r\n}\r\nfunction callback2() {\t\r\n}\r\n{code}\r\nIf testing this on Android it will correctly show the alert when clicking the button. On iOS it will not.\r\n",
