Could some one could explain me or give me a hand.
thanks in advance

Here is the code that I was working:

.controller('loa', function($scope, $ionicModal) {

// MAPAS ------------------------------------------------------------>
  $ionicModal.fromTemplateUrl('templates/calama.html', {
    scope: $scope
  }).then(function(modal) {
    $scope.modal1 = modal;
      }, {
    animation: 'slide-in-down',
    focusFirstInput: true,
    scope: $scope

  $scope.cierra1 = function() {

  $scope.mapaCalama = function() {
    L.mapbox.accessToken = 'pk.xxxxxx';
    var map ='map')
        .setView([-22.4562, -68.9249], 6)


        L.mapbox.featureLayer('itelius.xxxxxx').on('ready', function(e) {
        var clusterGroup = new L.MarkerClusterGroup();
       { clusterGroup.addLayer(layer); });


I tested with leafleft and its the same problem. I think is the CSS styles.
