why does the keyword ‘this’ not work with a background-image in my code [duplicate]

i want to put a background image in a div and it works well with the classname but not with the keyword “this”. how is this possible and what are the solutions?

 $('#txtElement1').on('keypress', () =>{
                    if(event.code == "Enter"){
                        const invoerTextveld = $('#txtElement1').val();
                        $('ul').append('<div class="outputCheck"></div> <li class="liText">' + invoerTextveld + '</li>' + '<hr class="hr">');
                       
                        $('.outputCheck').on('click', () =>{
                            console.log(this)
                           $(this).css('background-image', 'url(images/Group4.png)');
                        })
                    } 
            })
