Update event handler setters to travers view and context.
Update event handler setters to travers view and context.

InteractiveView events, like "click," "tap," "hover," etc., can have
function handlers, or be set to a string name. If using a string,
when the handler is set, it attempts to find a matching handler by
traversing the view and the view's context to find a matching
named-handler. The view context is given precedence.
