How to use ng-click in this way?

It's probably wrong to do it this way, but only then did I find datatable functionality.

<div class="panel-body">
    <script type="text/javascript">
        jQuery(document).ready(function($)
        {
            $("#example-1").DataTable({
                "ajax": {
                "url": "http://162.100.100.100/proyecto/public/ws/usuarios",
                "dataSrc": "records"
                },
                "columns": [
                    { "data": "id" },
                    { "data": "nombre1" },
                    { "data": "apellido1" },
                    { "data": "usuario" },
                    { "data": "idtipousuario" },
                    { "defaultContent": "<button class='btn btn-icon btn-info' ng-click='openModal(dataUsuario,'modal-2', 'lg');'><i class='fa-edit'></i></button>" }   
                ]
            });

             $('#example-1').on( 'click', 'button', function () {
                        //var data = table.row( $(this).parents('tr') ).data();
                       console.log("Mostrar Modal")
               });
        });
    </script>

For every record I filled in the table, I add a button

"defaultContent": "<button class='btn btn-icon btn-info' ng-click='openModal(dataUsuario,'modal-2', 'lg');'><i class='fa-edit'></i></button>"

How can I do with this button using ng-click to show a modal ?. Previously I filled the table with ng-repeat, but I lost the page, looking for the datatable.

How could I do this, or how else can I do it and if it is not possible, thank you very much. thank you very much.
