I am new to angular and as a first project I am trying to build a system that highlights and iterates over a row then onclick iterates over a column.
for some reason the number don't change in my $interval I think it is a silly mistake( it might be because I am making too many calls to the json)
the values that I want that should change are $scope.rowSelected and $scope.columnSelected
the error message is
angular.js:13642 TypeError: fn is not a function
at callback (angular.js:12456)
at Scope.$eval (angular.js:17378)
at Scope.$digest (angular.js:17191)
at Scope.$apply (angular.js:17486)
at tick (angular.js:12446)
Here is my view

here is the module
var App = angular.module('App', []);
var theLanguage = 'english';

$scope.language = res.data;
$log.log($scope.language);
});
$scope.letterSelectedForText;
$scope.rowOrcolumn = "row";
$scope.rowSelected = 0;
$scope.columnSelected = 0;
//needs to able to pas function how done in angular
$scope.callAtInterval = function() {
console.log("$scope.callAtInterval - Interval occurred");
if ($scope.rowOrcolumn == "row") {
$scope.rowSelected = $scope.rowSelected + 1;
}else if($scope.rowOrcolumn == column){

//var highlighted = angular.element(element.getElementsByClassName("btn-danger"));
//alert($scope.highlightedLetter = highlighted.text());
$log.log($scope.highlightedLetter = highlighted.text())
});
Any help would be appreciated also if someone has a tip or two I would also appreciate it.
