UI Bootstrap Typeahead is not displaying the values returned async

I am trying to do an autocomplete search using UI Bootstrap Typeahead to select a data from a database.

My service returns data in my response, but data are not listed in the component.

When I put a breakpoint in the component code , the list is there and when I continue to debug the list is displayed, but if it runs without breakpoints , the list is not displayed.

HTML

  <input id="inputInstalation" 
         ng-model="profile.instalation" 
         typeahead-editable="false" 
         typeahead="installation as installation.name for installation in searchInstallation($viewValue)" 
         typeahead-input-formatter="formatLabel($model)" 
         ng-required="true">

Controller

$scope.searchInstallation = function(text){

    return $http.get('/api/installations/name/' + text).then(function(response){
        return response.data;
      });
  };

$scope.formatLabel = function(model){
    return model ? model.name : "";
  };

API NodeJS - DB Mongo

exports.findByName = function(req, res){
  var connection =  getConnection();
  var Installation = getInstallationModel(connection);

  Installation.find({name: new RegExp(req.params.name, "i")}, function (err, result) {
    connection.close();
    if(err) throw err;
    res.json(result);
  });
};

I found the problem, I'm using the https://github.com/McNull/angular-block-ui and it conflicts with the component.

Solution : I created a requestFilter from angular blockui to don't block requests sent the component to API .
