sails.js view does not load

I made a controller which get data from a rest api and serializes them to .xls file.

In my web view I have a button with "Create xls data" which call my controller. Then my controller sierialises and reload this view with the xls download link and a "Download data" button.

My view import_export_data_page.ejs:
At start button "Create xls data" is displayed.

<%

if(typeof link == 'undefined'){
%>
<button type="button" class="btn btn-primary" id="button_get_xls_file">Create xls data</button>
<%
}else {
%>
<a href="<%= link %>"><button type="button" class="btn btn-primary"></button></a>
<%
}
%>

<script type="text/javascript">
$('#button_get_xls_file').click(function(){
var projectName = getCurrentServiceName(currentService);
$.get( "/api/export_xls_data", { url : currentService, projectname :     projectName} ).done(function( data ) {
  });
});

</script>

In my controller : 

exportXLS : function(req,res)
{
    var request = require('request');
    var categories;
    //get informations
     request(url + "/places", function (error, response, body) {
          categories = JSON.parse(body);
         /*
         * Parsing tacks 3 seconds max
         */
        //if file exists delete and create file
        fs.exists(fileName, function (exists) {
                if(exists){
                    fs.unlinkSync(fileName);
                }
                fs.writeFile(fileName, xls, 'binary',function(err){
                if(err){
                      console.log(err);
                      res.status(500);
                     return res.send("");
                }else{
                    var downloadLink = req.headers.host+'/xls/'+currentProject.split(' ').join('')+'_data.xls';
                     console.log(downloadLink);
                     return res.view('import_export_data_page',{link : downloadLink});
                    });
                }); 

    }

}

My file is created. My link works but my view is not reloaded.

Your view is not reloaded because your making an AJAX call. There is nothing in your code to tell the page to reload the view.

I think you want to change this:

$.get( "/api/export_xls_data", { url : currentService, projectname :     projectName} ).done(function( data ) {});

to: 

window.location.href = '/api/export_xls_data?url=' + currentService + '&projectname=' + projectName
