this.on = {};
this.on["myEventType"] = function(data, next) {

    if (data.someFiled === "anyValue") {
        console.log("got it");

If event should be handled by all controllers in any DOM branches and level SV.emmit can be used Like this:

SV.emmit("eventType", {someField: "anyValue"});

Emmit / Fire example:

<script> 
    SV.controller('c1', function(el) {
        this.on = {};
        this.on["e1"] = function(data, next) {
            console.log("c1: " + data);    
        }
        this.on["e2"] = function(data, next) {
            console.log("c1: " + data);    
        }
    });
    SV.controller('c2', function(el) {
        this.on = {};
        this.on["e1"] = function(data, next) {
            console.log("c2: " + data);
            if (data == 1) next();
        }
    });
    SV.controller('c3', function(el) {
        SV.fire(el, "e1", 1);
        console.log("---");
        SV.fire(el, "e1", 1.1);
        console.log("---");
        SV.fire(el, "e2", 2);
        console.log("---");
        SV.emmit("e1", 1.2);
    });
</script>

<div sv-controller="c1">
    <div sv-controller="c2">
        <div sv-controller="c3"></div>
    </div>
</div>

will produce the following in js console:

c2: 1
