Change Button's size of Button Inside A Dialog

Frappe Framework Custom Script
1

I have a dialog box and inside that I created a custom button Named Save. On v10 I was able to change class of button using jquery but same isn’t working on v11. This is what I was using in version 10

$("Button[data-fieldname=send1]").addClass("btn-danger");

How to approach for the same in v11.
Here’s the preview of field (button) inside dialog (both of 10 and 11)
v10 v11

Found the issue. If you do setTimeout to 1 sec it will work. I don’t know why is that. Somebody help.
