Angular's built-in jqLite doesn't support namespace for unbind/off. So If I use unbind/off its completely wipes out all the events attached to an element.
How do I unbind/off the specific event handler from an event in angularjs?

var listnerFn = function (){} // listener function.
angular.element(el).on('click', listenerFn) // event registration.
angular.element(el).off('click', listenerFn) // event de registration.
where el is the element reference on which events need to be registered.
click.myNamespace or just .myNamespace.
