Button click event implementation in angular2

Question

 As part of my curriculum, I am implementing a project with the technologies - Angular2, webapi, C#, and bootstrap.  In my project, I have developed 3 components and using them as nav tabs and defined routing configuration. When the user clicks on each tab the respective tab has radio button selection and upon radio button selection related data is displayed in tabular format. Until this point, I am able to implement successfully.

 

Now, I want to implement Button click event. A button should be displayed after table view only when the user selects the radio button and I am stuck here implementing button click event.

 

Can some expertise help me in achieving this? 

 

Thanks in advance.
