AngularJS - Pass an ajax request to another controller

I have two tables in my page, and upon clicking on a row on the first table, i wanted to call an ajax request to update the second table.

I'm trying to do this with two controllers, each of them with an ng-repeat filling the rows with values. I've burned out every neuron i could afford and I'm still stumped.

This is my code

app.controller("TermsCtrl", function($scope, $http) {
    $http.get('json.php').then(function(res) {
        $scope.wordfreq = res.data;
        $scope.decodeURIComponent = decodeURIComponent;
        $scope.unescape = unescape;
    });
    $scope.go = function(id) { // This makes the rows clickable and calls the next results
        return $http.get('json2.php?word=' + id).then(function(result) {
            secondtable = result.data;
            console.log(secondtable); // I see the objects!
            return secondtable;
        });
    };
});
app.controller("TermsCtrl2", function($scope, secondtable) {
    $scope.secondfeq = secondtable;
    console.log(scope.secondfeq); // No dice
});

Any ideas how to get the secondtable results from the click into the TermsCtrl2 controller?

cheers
