Passing data between functions in a JavaScript file

I need some guidance on implementing an angularjs google column chart. Specifically, I have a requirement to transfer the value from one JavaScript function to another variable defined in a separate JavaScript function.

Here is an example snippet of code from myController.js:

   var globalID;
   app.controller('myChart',['$rootScope','$scope','$uibModal','myService',function($rootScope,$scope,$uibModal,myService)  {
    $scope.chart = {};
    $scope.chart.options = {
        "title": "Summary API Tests",
        'fontSize': '12',
        "isStacked": "true",
        colors: ['blue', 'cyan', 'red'],
        axisFontSize : 8,
    };
    $scope.chart.type = "ColumnChart";
    $scope.function2= function( event ) {
         alert('in function2');
         /* want to assign the value of val from below lines to globalID */
         /* globalID = val; */
    };
    /* I want to invoke below lines in $scope.chartClick*/
    $scope.function1= function (selectedItem) {
            $scope.chart.data.rows[selectedItem.row].c[0].v;
            val = $scope.chart.data.rows[selectedItem.row].c[0].v;

            alert("inside function1: " + val);
        };

        //some more logic below


        });

In the given JavaScript file, my goal is to pass the value of `val` from `$scope.function1` to `globalID` inside `function2`.

Assign a value to the scope

$scope.assignValue = function (selectedItem) {
    $scope.chart.data.rows[selectedItem.row].c[0].v;
    $scope.selectedItemId = $scope.chart.data.rows[selectedItem.row].c[0].v;
    alert("Selected item ID: " + $scope.selectedItemId);
};

$scope.chartClicked = function( event ) {
     alert('Chart clicked');
     if($scope.selectedItemId){
         // Implement your logic when an item is selected
     }
};
