Splunk JS Stack: custom visualization issue rendering myviz

[bizsplunk]

hi team,
i have issue with custom visualization. i use Splunk JS stack to render myviz, but get this error:
"Error: Visualization "viz_tutorial_app.myRadialMeter" has not been registered with the system. It may not exist or might not be visible for the current user or app."

my code example:

    <panel>
      <html>
        <div id="mycustomviz"></div>
      </html>
    </panel>



datatest.js:
require([
    'underscore',
    'jquery',
    'splunkjs/mvc',
    'splunkjs/mvc/visualizationregistry',
    'splunkjs/mvc/searchmanager',
    'splunkjs/mvc/simplexml/ready!'],
function(_, $, mvc, VisualizationRegistry, SearchManager){

        var mysearch = new SearchManager({
            id: "search19",
            earliest_time: "-1y@y",
            latest_time: "now",
            search: "index=zabbix | stats count by hostname",
            preview: true,
            cache: true,
        });

        var customViz = VisualizationRegistry.getVisualizer('viz_tutorial_app', 'myRadialMeter');
        var mytimeline = new customViz({
            id: "timeline1",
            managerid: "search19",
            el: $("#mycustomviz")
        }).render();
    }
);
