jQuery event maps with delegation?

example.js

var $container = $(".container");

// Woo delegated event handlers (but I have to call on() twice)
$container.on("click", ".control1", function () {
    // blah
});

$container.on("mouseleave", ".control2", function () {
    // blah
});

// Woo event map (but how can I delegate the event handler as above?)
$container.on({
    click: function () {
        // blah
    },
    mouseleave: function () {
        // blah
    }
});

// OK on second thought, this is easy to do with an if
$container.on({
    click: function ( event ) {
        $t = $(event.target)
        if ( $t.hasClass( '.control1' ) ) {
          // blah
        }
        if ( $t.hasClass( '.control2' ) ) {
          // blah
        }
    }
});
