How to change the text of a collection button or change the text of one of the collectioned button

Hi all,

I'm a junior web developper and for the need of my company we use a DT in our new web-application
I use collection them to filter data with hidden colunms and hidden input which contains strings and now I want to change the text of one of my collection button to show the user which filter is enable so I know that we can use this.text() to change the text of simple buttons whitout collection system and now I'm looking for a way to apply this system to a collection button or if you folks have a better idea.

Thanks.

(Sorry for my approximate english)
