    For security reasons, the events in the html code we inserted and the bound ng-model will not work.

    If you want it to work, you need to use angular’s ​​$compile service

    I usually use a directive when processing

    javascriptangular.module(...).directive('jxbBindCompiledHtml', function ($compile) {
  'use strict';

  return {
    template: '

<p></p>

',
    scope: {
      rawHtml: '=jxbBindCompiledHtml'
    },
    link: function (scope, elem, attrs) {
      scope.$watch('rawHtml', function (value) {

        if (!value) {
          return;
        }

        // we want to use the scope OUTSIDE of this directive
        // (which itself is an isolate scope).
        var newElem = $compile($.parseHTML(value))(scope.$parent);
        elem.contents().remove();
        elem.append(newElem);
      });
    }
  };
});

    html

    html<p jxb-bind-compiled-html="htmlvariable">
</p>

    htmlvariable is the html code variable that needs to be inserted

        });
        angular.bootstrap(document, ['app']);
    </script>
</body>
</html>

    I wrote an example, as above.
