[SOLVED] Use HTML from item value

Ok.
With help of: https://stackoverflow.com/a/19705096/9077523, Add angularjs code in template widget, Angular Controllers, Custom widget: Angular radial color picker I got the following:

HabPanel template widget with:

<div oc-lazy-load="['/static/myLog.js']">
  <div ng-bind-html="itemValue('String_MyLog') | unsafe">
  </div
</div>

openHAB-conf/html/myLog.js with:

var app = angular.module('app.mylog', [])

app.filter('unsafe', function($sce) {
    return $sce.trustAsHtml;
});
