Doc for component-level action has a coding mistake

[bruceesmith]

In Component-level Actions the body of function OnMount is incorrect

func (h *hello) OnMount(ctx app.Context) { ctx.Handle("greet") // Registering action handler. }

It should be

func (h *hello) OnMount(ctx app.Context) { ctx.Handle("greet", handleGreet) // Registering action handler. }

Correction. Code should be

func (h *hello) OnMount(ctx app.Context) { ctx.Handle("greet", h.handleGreet) // Registering action handler. }
