AngularJS is failing to properly register custom directives

Looking to enhance the SEO caching capabilities of my AngularJS website, I've embarked on implementing a couple of directives for custom page titles and descriptions.

Incorporated within my app config (

angular.module('website', [...'website.directives'...])
) is a module called
angular.module('website.directives', [])
, housing the necessary directives. The directive file appears as follows:

angular.module('website.directives').directive('viewTitle', function() {
    restrict = 'E';
    link($scope, element) {
        console.log("Linking view title.");
        var text = element.text();
        element.remove();
        $('html head title').text(text);
    }
});

angular.module('website.directives').directive('viewDesc', function() {
    restrict = 'E';
    link($scope, element) {
        console.log("Linking view description.");
        var text = element.text();
        element.remove();
        $('html head meta[name=description]').attr('content', text);
    }
});

In template usage, the directives are applied as expected:

<view-title>My Website</view-title>
<view-desc>A short description of my website.</view-desc>

Unfortunately, the directives do not seem to be functioning correctly as intended. Neither does the expected text removal occur nor do the title/description updates take place. Surprisingly, the console statements in the link functions remain uncalled. The reason behind why the directives fail to execute is uncertain to me.

I am willing to provide any additional details required to troubleshoot the issue further. Thank you!

EDIT: Regrettably, an attempt was made to translate the TypeScript directive into JavaScript in order to simplify readability, but considering its negative aftermath, it was, in fact, counterintuitive. It would have been more sensible to solely furnish the code without alterations. Here's how the directive code actually looks like:

export class ViewTitleDirective implements ng.IDirective {
    restrict = 'E';
    link($scope, element: JQuery) {
        console.log("Linking view title.");
        var text = element.text();
        element.remove();
        $('html head title').text(text);
    }
}

export class ViewDescriptionDirective implements ng.IDirective {
    restrict = 'E';
    link($scope, element: JQuery) {
        console.log("Linking view description.");
        var text = element.text();
        element.remove();
        $('html head meta[name=description]').attr('content', text);
    }
}

angular.module('website.directives').directive('viewTitle', () => ViewTitleDirective);
angular.module('website.directives').directive('viewDesc', () => ViewDescriptionDirective);

It seems like the issue might be related to how you are initializing your application within the body tag.

For example: <body ng-app="myApp">

Consider moving this initialization to the html tag instead.

<html ng-app="myApp">

By doing this, your <head> will also be included in the application's DOM compilation process, potentially allowing your directive to work properly with title and content tags.
