How do you update the Page length button caption?

Hi,

regarding this
https://datatables.net/extensions/buttons/examples/initialisation/pageLength.html

How can you update the button caption?
I tried both
"lengthMenu": [
[10,20,50,100,200,400],
[10,20,50,100,200,400]
],
"sLengthMenu": "MENU",
and
"lengthMenu": 'Display <select>'+
'<option value="10">10</option>'+
'<option value="20">20</option>'+
'<option value="30">30</option>'+
'<option value="40">40</option>'+
'<option value="50">50</option>'+
'<option value="-1">All</option>'+
'</select> records'

The first worked button-wise, but the caption didn't changed (showed "Show 10 rows").
The second just didn't worked.

Thanks,
Yishay

    Use the text option of the pageLength button type.

    Hi Allan,

    I'm sorry, I forgot to mention this in my previous post, we already done that:

              {
                text:$translate.instant(''),
                extend: "pageLength",
                className: "fa fa-arrows-v",
              }
    

    Thanks,
    Yishay

    $translate.instant('')

    Does that resolve to be an empty string? If so, that might be the issue.

    Hi Allan,

    that seems to be the issue.
    It still seems that both ways defined in the documentation doesn't work (these are the only way to show on the button the number of records selected).

    Answer ✓

    It looks like there is a bug that the button text is overridden when the value is changed. It work for me on first load, but not after a change. That is a bug that will need to be addressed.

    Using the language.buttons.pageLength option works:

            language: {
                buttons: {
                    pageLength: '%d'
                }
            }
