Call Process Client Side

Hi Community,

I want to call a process on the 
client side and when it ends, for example, update certain values ​​of the page. 
Is it possible using the callback? 
The callback works but the page with the caption of loading remains. I Have this example:

var someFunction = function (a) { 

                                    

                                    this.loadSchemaCaptionByName("UsrApproveBSRankedCompare", function(caption) {

                                                this._showSuccessfullyRunProcessPopup("The process has been completed");

                                            }, this);

                                    

                                };

                                this.executeProcess(args , someFunction)

executeProcess: function(sysProcessName, callback) {

                ProcessModuleUtilities.responseCallback = callback;

                ProcessModuleUtilities.executeProcess(sysProcessName)

            }    

Thank you!
