Why doesn't the demo example with "data-table" from off. site framework "Lumx"?

Question

Angular

I'm trying to run a demo from off. site, but it turns out with great difficulty. I've been poking around for a few days, but I haven't made much progress.
It was possible to start displaying data in the "data-table", but sorting by fields does not work, and additional buttons do not appear after opening records (for editing and deleting).
This is how it works for me:
codepen.io/okuznetsov/pen/EZBGGZ
And this is in the example on off. website:
ui.lumapps.com/components/data-table
files off. demo here - https://github.com/lumapps/lumX/
My index.html

<div ng-app="notes">

    <div ng-controller="MainController">

        <div class="toolbar has-divider has-divider--dark">
            <div class="toolbar__label pl">
                <span>{{ selectedRows.length || 0 }} selected item(s) </span>
            </div>
            <div class="toolbar__right">
                <lx-button lx-size="l" lx-color="grey" lx-type="icon" ng-if="selectedRows.length === 1">
                    <i class="mdi mdi-pencil"></i>
                </lx-button>

                <lx-button lx-size="l" lx-color="grey" lx-type="icon" ng-if="selectedRows.length >= 1">
                    <i class="mdi mdi-delete"></i>
                </lx-button>
            </div>
        </div>

        <lx-data-table id="lolo" lx-selectable="true" lx-thead="dataTableThead" lx-tbody="dataTableTbody"></lx-data-table>

    </div>
