var callbacks = $.Callbacks();



// add the function 'foo' to the list

callbacks.add( foo );



// fire the items on the list

callbacks.fire( 'hello' ); // outputs: 'foo: hello'

callbacks.fire( 'world '); // outputs: 'foo: world'



// add another function to the list

var bar = function( value ){

    console.log( 'bar:' + value );

} 



// add this function to the list

callbacks.add( bar );



// fire the items on the list again

callbacks.fire( 'hello again' );

// outputs:

// 'foo: hello again'

// 'bar: hello again'
