Reload an Angularjs table from time to time

Question

My Angularjs page displays a table with data coming from a JSON. What I want is that the table is updated from time to time, because the data is updated according to the second and I show only the last 10.

<tr ng-repeat="linha in linhas">
  <td ><abbr title="{{linha.descricao}}"> <a href=xxx.php?id_chamado={{linha.chamado}}>{{linha.chamado}}</a> </abbr>  </td>  
  <td >{{linha.data}}</td>
  <td >{{linha.nome}}</td>
  <td >{{linha.acao}}</td>
  <td >{{linha.cliente}}</td>   
  <td ><span class="label label-success">{{linha.sistema}}</span></td>
</tr>

Is there any simple way to reach this goal ?

My controller, everything works perfect in the page load. I just don’t know how to re-invoke this function inside the controller.

// JavaScript Document
var app = angular.module('sadApp', []);
app.controller('sadCtrl', function ($scope, $http) {
    $http.get('http://192.168.0.14/a/historicochamadologlidosJson.php').
    success(function(data,  status, headers, config) {
        $scope.linhas = data;
    })
});

I’ve tried this code here:

angular.element(document.getElementById('MainWrap')).scope().$apply();

where Mainwrap is the id of div:

<div ng-controller="sadCtrl" id="MainWrap">

You can try the code below. What I did was to wrap in a "private" function the section that searches the data, and call this function both at startup, and at intervals determined by a timer:

// JavaScript Document
var app = angular.module('sadApp', []);
app.controller('sadCtrl', function ($scope, $http) {

    // Função que atualiza os dados
    // Somente disponível aqui dentro, não é método público
    function atualizaDados() {
        $http.get('http://192.168.0.14/a/historicochamadologlidosJson.php').
        success(function(data,  status, headers, config) {
            $scope.linhas = data;
        });
    }

    // Executa a função na inicalização
    atualizaDados();

    // Executa novamente a cada 60 segundos (60.000ms)
    // Altere o intervalo para o que achar mais adequado.
    setInterval(atualizaDados, 60000);
});
