it helps some times I am loading checkboxes in a loop. I have difficulties in setting the states for the dynamic checkboxes. , Constructor:
constructor(props) {
  this.state = {
    checkBoxObj: {}
<input type="checkbox" 
     checked = {this.state.checkBoxObj[i] || false}
     onChange={() => this.passMemberID(i)}
passMemberID = (i) => {
    checkBoxObj: {
      ...this.state.checkBoxObj, ...{[i]: !this.state.checkBoxObj[i]}

Hope that helps , So you want all inputs whose ids start with cbProducts?
$("form input[id^='cbProducts']");
_ctl = $("form input[id*='cbProducts']");
$("form input[id='cbProducts' + elm]");
$("#cbProducts" + elm);

react setState with dynamic key

wish of those help Basic rule is:
We can use Computed property names concept and use any js expression to compute the object property name dynamically. For that we need to put the expression inside [].
var obj = {
   [10 * 20 + 1 - 5]: "Hello"

console.log('obj = ', obj);
onChange(e) {
      [e.target.id]: e.target.value
onChange(e) {
    let obj = {};
    obj[e.target.id] = e.target.value

react native dynamic setstate with string and dynamic index

may help you . For React Native to detect changes to state and thus re-render your view you must call setState in immutable manner. So in your case try the following:
//copy state
const newState = {...this.state};
//access property - "key1, key2, etc" whatever index is.
newState['key'+index] = 1;
// set new state

Using a dynamic key to setState in React

Does that help When setting state with a dynamic key, you need to wrap the key within [] like
  onTextChange={(text, key) => {
      event: {
        [key]: text

dynamic setState to add new dynamic property in react

it should still fix some issue If I understood what you're trying to do correctly, you just needed to spread the value object inside of your map:
onChange = (e, i) => {
      items: this.state.items.map(o => ({
        value: {
          ...o.value,  // <- this
          [this.state.lang[i]]: e.target.value
