add the on-click attribute, to add a basic handler to the element.
add the on-change attribute, to add a basic handler to the element.
most event names have easy names but this library may accept almost any type of event name. e.g. show.bs.modal
While most event names are lowercase, some events may use some capital letters in their name (or weird characters such as *). In these cases we can use the :map suffix to add a translation.
In this example, the on-capitalevent attribute will be translated to on-CapitalEvent event name
(*) Attributes always appear in lowercase in the DOM so for javascript it does not have effect to write the attribute as on-CapitalEvent directly: it will attive to javascript as on-capitalevent
