With many same component initialized on same page, how to know which component's on api

[ilker çatak]

I have many posts on a same page so if user click on a button i want to post some data .The problem is that i cant get exact component with semantic ui. İ want to solve this issue genericly. Every component has unique data attribute. Let me know if there is away something like that. "data:{id:this.dataAttribute}". Thank you
