To Delete file form Server, you need to use onMediaDelete but usage varies with different summernote versions, sometimes difficult to find in the docs

FOR SUMMERNOTE 0.6.x

$(document).ready(function() {
    $('.summernote').summernote({
        height: "300px",
         onMediaDelete : function($target, editor, $editable) {
         alert($target.context.dataset.filename);         
         $target.remove();
    }
    });
});

FOR SUMMERNOTE 0.7.x

$(document).ready(function() {
    $('.summernote').summernote({
        height: "300px",
        onMediaDelete : function(target) {
                deleteFile(target[0].src);
            }

    });
});

FOR SUMMERNOTE 0.8.x (Use Callbacks)

$(document).ready(function() {
    $('#summernote').summernote({
        height: "300px",
        callbacks: {
            onImageUpload: function(files) {
                uploadFile(files[0]);
            },

            onMediaDelete : function(target) {
                // alert(target[0].src) 
                deleteFile(target[0].src);
            }
        }
    });
});
