ng-table: Error: settings.$scope.$emit is not a function

Hey there, just wanted to start off by saying how much I appreciate the project and the work that’s been going into it.

Anyways, I seem to be having a really weird error. Basically, I can run $scope.tableParams.reload() twice with no problem, but on the third execution, and every following one, I get the following error:

TypeError: Cannot set property '$data' of null at [removed]/ng-table.js:411:55

I believe this is all the relevant code, but if anything is missing let me know:

$scope.lookupAddress = function(address){       
    var url = 'https://blockchain.info/multiaddr?cors=true&active='+address;
    $scope.loading = true;
    $scope.clearTableData();
    $http.get(url).success(function(data){
        $scope.loading = false;
        $scope.loaded = true;
        $scope.loadError = false;
        glob = data;

        //Removed code that processes the response. 

        };
        //Enables new data to be loaded, e.g. on a new address.
        //Pretty sure it's not working right now.
        if ($scope.tableParams){
            $scope.tableParams.reload();
        } 
        data = transactions; //this data var is what is called by the tables. Unsure if can remove.
        $scope.tableParams = new ngTableParams({
            page: 1,            
            count: 5,           // items per page
            sorting: {
                Date: 'desc' 
            }
        }, {
            total: transactions.length, 
            getData: function($defer, params) {
                data = transactions;
                var orderedData = params.sorting() ? $filter('orderBy')(data, params.orderBy()) : data;
                $defer.resolve(orderedData.slice((params.page() - 1) * params.count(), params.page() * params.count()));

            }
        });
    }).
    error(function(data){
        $scope.loadError = true;
    });
}

$scope.clearTableData = function(){
    transactions = [];
    $scope.output = {}
    if ($scope.tableParams){
            $scope.tableParams.reload();
    } 
}
