var arr = [{
    value: 'a'
}];
var getTest = function() {
    var toRet;
    jQuery.each(arr, function(i, val) {
        if (val.value == "a") {
            toRet = val;
        }
    });
    return toRet;
}

alert(getTest().value);

jQuery.each is actually a function and you are returning value there and not to your function getTest(). This is working solution.
