Artem,

Artem thanks for your reply.

I am going to change Inputs` value on ContactPageV2 page when I click costum button. Like I when I clicked button Age's value should change to 24.

Hello, 

You could use the next method:

Insert the code below into the click handler function of your button:

this.set("Age", 24);

Thank you,

Artem.
