How to set state based on different functions in react using firebase - reactjs

Question

I am trying to make a template system in my survey tool and set the state to a json object which will be pushed onto the firebase database, but I want to know how to change the state based on which template i choose in the previous page:
I have 4 templates:
Blank
Board
Board Member
Chairperson
I am showing these as buttons and when any of them is clicked the corresponding handlers run
<button
onClick={function(event) {
props.clicked();
notify();
}}
className={classes.Blank}
>
Blank Survey
</button>
<button onClick={props.board} className={classes.Board}>
Board Survey
</button>
<button onClick={props.chair} className={classes.Chair}>
Chairperson Survey
</button>
<button onClick={props.member} className={classes.Member}>
Board Member Survey
</button>
Now I use the props to assign them to corresponding handlers:
<NewSurveyView
clicked={this.clickHandler}
board={this.boardHandler}
chair={this.chairHandler}
member={this.memberHandler}
isLoading={this.props.loading}
error={this.props.isError}
/>
These are the three functions I am using to fetch the templates:
const fetchBoardMember = async () => {
const res = await axios.get(
"/surveys/ckb0kmt3n000e3g5rmjnfw4go/content/questions.json"
);
return res.data;
};
const fetchBoard = async () => {
const res = await axios.get(
"/surveys/ckb24goc800013g5r7j8igrk3/content/questions.json"
);
return res.data;
};
const fetchChair = async () => {
const res = await axios.get(
"/surveys/ckb24gt3s00053g5rrf60353r/content/questions.json"
);
return res.data;
};
Next, I create an object with all the info which i want to push (this is for Board Template):
const board = {
title: "Your Survey Title",
subTitle: "Your Survey Description",
creatorDate: new Date(),
lastModified: new Date(),
questions: fetchBoard().then(questions => {
this.setState(state => ({
...state,
content: {
...state.content,
questions
}
}));
}),
submitting: true
};
Setting the state:
this.setState({
_id: newId(),
content: board,
userId: this.props.user_Id
});
Now my question is, how do I change the variable used based on the template chosen by using the buttons?
