jQuery enable checkbox

Hi
I have a disabled checkbox in a table and want to enable it when the edit button is pressed. Not having much luck with this code.

        $(".edit").click(function(){
            if ($(this).hasClass("save")){
                console.log("save");
            }else{
                console.log("edit");
                $(this).closest("tr").find("td").each(function(){
                    if ($(this).index()!=0  && $(this).index()!=10){
                        if ($(this).hasClass("delivery")){

                            $(this).closest("input[type=\"checkbox\"]").prop({
                                disabled:false

                            });
                        }else{
                            $(this).html("<input type=\"text\" class=\"edit" + $(this).attr('class') + "\" name=\"" + $(this).attr('class') + "\" value=\""+$(this).text()+"\">")
                        }                                
                    } 
                });
