How do I call a function from AngularJS controller from inside the DataTable

Question

I have a datatable being generated by JSON array coming from a specific url. I also have a hypderlink on each column that redirects me to the next page either.

Now all I have to do is to call another function from inside the same angularjs controller.

Code for DataTable, with hyperlink columns, PLEASE REFER TO THE if BLOCK for concerned citation:

            $.getJSON('http://blahblahblah/company/all', function(data) {

            var companyId = null;
            $('#companies').DataTable({
                "aaData": data,
                "aoColumns": [
                    {"mDataProp":"companyId", "render": function(data, type, row, meta) {
                        if( type==='display' ) {
                            companyId = data;
                            data = '<a href="' + "/pages/company?companyId=" +companyId+ '">' + data + '</a>';
                            // call a function from this file when click on the above generated link, JUST HERE
                        }
                        return data;
                    }},
                    {"mDataProp":"legalName", "render": function(data, type, row, meta) {
                        if( type==='display' ) {
                            data = '<a href="' + "/pages/company?companyId=" +companyId+ '">' + data + '</a>';
                            // call a function from this file when click on the above generated link, JUST HERE
                        }
                        return data;
                    }}

                ]
            });

        });

Code for a function defined in the same controller:

        $scope.findCompanyById = function() {

        $http.get(
                'http://blahblahblah/company/find?id='
                        + $location.search().companyId).

        then(function(response) {
            $scope.company.companyInfo = response.data;
        });


    };

I am waiting for your kind response, Thanks.
