Add dynamic HTML from JavaScript in Angular 2/4/5 and bind events

Question

I am trying to add new HTML code via AJAX to an Angular 5 app and add click event to the elements. But the click event doesn't work as expected, I can't use the 2 way data-binding way because I am using the jQuery data-tables plugins and he add the HTML to the Dom and not the angular template.

I have tried:

<button  (click)='myClassFunction()'>Click!</button>  this line does nothing
<button  onclick='myClassFunction()'>Click!</button>  this line said myClassFunction is undefined
<button  onclick='this.myClassFunction()'>Click!</button> this line said myClassFunction is undefined

How can I bind this click event to my function?

Please use (click) instead of onClick in Angular

Angular is written in Typescript.

When you serve or build your application, this typescript application is then compiled, minified and uglified to native Javascript.

This means that your

(click)="myClassFunction()"

Will become something along the lines of

onclick="srgu.gferu()"

And as you can see, Angular won't recognize that.

It doesn't matter if you use JQuery or plugins : that is the way Angular works.

To do that, you will need to create window functions, or global functions.

myClassFunction() {
  // Create your window function, make it tslint compliant
  window['myWindowClassFunction'] = () => {
    // Your function's logic here
  };
}

Now, in your appended HTML, you need to write

<button  onclick='window.myWindowClassFunction()'>Click!</button>

Well I just explained you how you can do it, so yes it's possible :D But great if you succeed ! (Using JQuery with Angular is an anti-pattern though)
