Remove element with .remove jQuery

Well, as the title says, I'm trying to remove elements that I add to a div with .appendbut I can't.

The .append

$("#elPedido").append('<div class="lineasComanda">\
                         <div class="row" style="margin: 0px;">\
                            <div class="col-2 center" style="padding: 0px;">\
                               <img src="'+ resultProNormal.productNormal.foto +'" alt="" class="imgComanda">\
                            </div>\
                            <div class="col-5" style="padding: 0px;">\
                               <h2>'+ resultProNormal.productNormal.name +'</h2>\
                               <small>Familiar</small>\
                            </div>\
                            <div class="col-1" style="padding: 0px;">\
                                <h5>x1</h5>\
                            </div>\
                            <div class="col-2 txtRight" style="padding: 0px;">\
                                <h5>'+ resultProNormal.productNormal.precio +'€</h5>\
                            </div>\
                            <div class="col-2 center" style="padding: 0px;">\
                                <div class="deleteFila"><a class="delete"><i class="far fa-trash-alt"></i></a></div>\
                                </div>\
                            </div>\
                         </div>');

The function to remove

$("body").on("click",".deleteFila", function(){
  var indice = $(".deleteFila").index(this);
  console.log(indice);
  //carrito.splice(indice, 1);
  $(this).parent(".lineasComanda").remove();
});

If it brings me the console.log(indice)index correctly, that is, the function is working. If, on the contrary, appendI remove all of .div rowthem and colsleave only one div inside of lineasComandait, it eliminates it without problems.

I don't know how to get me to catch all those divs.

Cheers

I have solved it like this but I don't know if it is right because I don't understand why it works like that.

$(this).closest(".lineasComanda").remove();
