Is not a function error - JavaScript es6 class structure : <p>having issue - is not function error, with my code, here it is:</p>

<pre><code>import $ from 'jquery';
import gsap from 'greensock';

class IntroAnimations{
 constructor(){
    this.ctaEnter         = $('#cta-enter');
    this.loadContent      = $('.center-h-v');
    this.tlLoading        = new TimelineLite();
    this.animationTime    = .5;

    this.ctaEnter.click(function(){
        this.removeLoadContent(); //&lt;- error is here
    })
 }
removeLoadContent(){
    TweenLite.to(this.loadContent, this.animationTime, {autoAlpha: 0})
 }
}

export default IntroAnimations;
</code></pre>

<p>Error is when I call this.removeLoadContent();
Can someone help me explain why this is causing an error?</p>

<p>Thank you.</p>
