javascript return value of function binded as object value

Question

I can not return values bools / strings using the following convention.

<input id="lol" type="text" value="ahh" />

<script>
function test() {
    var flag = false;
    if ($('#lol').val()) {
        alert($('#lol').val()); //"sanity check - pass"
        flag = true;
    }
    return flag;
};

function modal() {};
var m = new modal();

modal.prototype.init = function(x) {
    this.input = x;
    this.modals = {};
    this.initModalFrames();
    this.executeLogic();
}

modal.prototype.initModalFrames = function() {
    for (i in this.input) {
        this.modals[i] = {
            handle :    this.input[i].handle,
            frame :     this.input[i].frame,
            logic :     this.input[i].logic ? this.input[i].logic : null
        };
    }
}

modal.prototype.executeLogic= function() {
    var s = this;
    $.each(this.modals, function(i, o) {
        if(s.modals[i].logic != null) {
            var x = s.modals[i].logic.call();
            if(x) {
                alert('true');
            }
            else {
                //Always evaluates to false
                alert('false');
            }
        }
    });
}

m.init([
      {handle: '#handle1', frame: '#frame2', logic: function() {test();}},
]);

</script>

The function does not seem to return anything and always evaluates to false. What am I doing wrong here?

Your logic handler should return the result of test execution:

{ handle: '#handle1', frame: '#frame2', logic: function() { return test(); } }

or simpler:

{ handle: '#handle1', frame: '#frame2', logic: test }
