How to capture change of date(s) for Kendo Scheduler?

I am working w/a C# MVC (5.2.2) App using Kendo.MVC (2015.3.930.545) on VS 2013 (.NET 4.5.1).

I need help capturing a start/end date change w/JS to then make the appropriate AJAX call to the server to refresh/update the scheduler.

I am getting the Kendo.Mvc.UI.Fluent.DataSourceEventBuilder does not contain a definition for 'Navigate' for this line of code:
e.Navigate()

and the Kendo.Mvc.UI.Fluent.SchedulerAjaxDataSourceBuilder<EPIMS.Models.TaskViewModel> does not contain a definition for 'Data'​" for this line of code:
Line 60: .DataSource(d => d
Line 61: .ServerOperation(true)
Line 62: .Read("Details", "Inspections").Data("getAdditionalData"))

Am I using outdated API calls?
