Per our discussion - this is the general approach we'd like to take for
the public facing API.
var MyComponent = React.createClass({
render: function() {
return <div onClick={this.myCallback} />;
},
myCallback: function() {
}
});

|
|
* - Automatically supporting the previous behavior in components that were

|
