Implement Custom Timeline View with Dynamic Length

The following example demonstrates how to implement a custom Timeline view in a Kendo UI Scheduler which allows to change its length dynamically.

Example
    Number of shown days: <select id="days">
                            <option>6</option>
                            <option selected>7</option>
                            <option>8</option>
                          </select>
    <div id="scheduler"></div>
    <script>
        var MyCustomTimelistView = kendo.ui.TimelineMonthView.extend({
          options: {
            name: "MyCustomTimelistView",
            title: "Timeline Week",
            selectedDateFormat: "{0:D} - {1:D}",
            selectedShortDateFormat: "{0:d} - {1:d}",
            majorTick: 1440,
            numberOfDays: 7
          },
          name: "MyCustomTimelistView",
          calculateDateRange: function() {
            //create the required number of days

            var start = this.options.date,
                //  start = kendo.date.dayOfWeek(selectedDate, this.calendarInfo().firstDay, -1),
                idx, length,
                dates = [];

            for (idx = 0, length = this.options.numberOfDays; idx < length; idx++) {
              dates.push(start);
              start = kendo.date.nextDay(start);
            }
            this._render(dates);
          },
          previousDate: function() {
            var date = new Date(this.startDate());

            date.setDate(date.getDate() - this.options.numberOfDays);

            return date
          }
        });

      $(function() {
        var scheduler = $("#scheduler").kendoScheduler({
