How to pass params to Dropdown component from semantic ui react?

I have react js code below where I put semantic ui react Dropdown component in a map. yoe is an array in state, I put value={yoe[i]}, but how can I have the index i being passed to the onChange prop? I tried the following, but the method onAddYoe seems doesn't recognize i. Can someone kindly help? Thanks!

              {specialties &&
                specialties.map((specialty, i) => {
                  return (
                    <div className="a-row" key={i}>
                      <div className="a-col-md-12">
                        <div className="a-text-box">
                          <label className="a-mb-5">
                            Years of experience in {specialty}
                          </label>
                          <br />
                          <Dropdown
                            placeholder="0-1 years"
                            fluid
                            selection
                            value={yoe[i]}
                            options={this.yoeList}
                            onChange={this.onAddYoe(i)}
                          />
                          {errors.email ? (
                            <span className="error">Email Required</span>
                          ) : null}
                        </div>
                      </div>
                    </div>
                  );
                })}

I don't know how you defined your onAddYoe but I am suspecting it is something like this.

function onAddYoe(i) {
  // do something based on i
}

Then you are using it on onChange like so, notice that onChange expects a function but here you are actually returning the result of the function.

<
  onChange={this.onAddYoe(i)}
/>

You should change your function to return a function like so:

function onAddYoe(i) {
  return () => {
    // do something based on i
  }
}
// or a shorter version on a functional component
const onAddYoe = (i) => () => {
  // do something based on i
}
