Firing an event in a renderer can cause an infinite rendering loop.
Don’t do this!
afterRender: function(cmp, helper) { this.superAfterRender(); $A.get("e.myns:mycmp").fire(); }
Instead, use the init hook to run a controller action after component construction but before rendering. Add this code to your component:
<aura:handler name="init" value="{!this}" action="{!c.doInit}"/>
For more details, see .Invoking Actions on Component Initialization.
You can’t use different actions for onclick and ontouchend events in a component. The framework translates touch-tap events into clicks and activates any onclick handlers that are present.
