Add Textbox on button click

Question

In my scenario I am building a tree structure.

There are three buttons:

• Button number 1 - for adding parent node
• Button number 2 - for adding child node
• Button number 3 - for removing it

There is a textbox which is entering the parent node.

When user enter a parent node and click on button number 2 then a textbox should come under the parent.

Number of times the button is clicked respective times textbox should be generated.

Tell me how to achieve this in MVC as I am new to MVC.
