Properties:
Previously only arbitrary DOM attribute bindings were supported via interpolation such as
`my-attribute="{{expression}}"` or `ng-attr-my-attribute="{{expression}}"`, and only a set of
distinct properties could be bound. `ng-prop-*` adds support for binding expressions to any DOM
properties. For example `ng-prop-foo="x"` will assign the value of the expression `x` to the
`foo` property, and re-assign whenever the expression `x` changes.
Events:
Previously only a distinct set of DOM events could be bound using directives such as `ng-click`,
`ng-blur` etc. `ng-on-*` adds support for binding expressions to any DOM event. For example
`ng-on-bar="barOccured($event)"` will add a listener to the "bar" event and invoke the
`barOccured($event)` expression.
Since HTML attributes are case-insensitive, property and event names are specified in snake_case
for `ng-prop-*` and `ng-on-*`. For example, to bind property `fooBar` use `ng-prop-foo_bar`, to
listen to event `fooBar` use `ng-on-foo_bar`.
