@rohithkumbharkar I have a different suggestion where to put this code that makes it much easier. If you look below in that class there is a public set keybinding(keybinding: string). I suggest to set the title in there because it gets computed there:

this.$label.title(title);
this.$badge.title(title);
this.$container.title(title); // <-- add it here

@bpasero Yup totally makes sense for some reason I thought I couldn't access $container in there. Made the changes
