The unit click event would replace default click event

[jessy1092]

So that can't get e which is react event parameter.

ex.

render: function() {
  return(
    <Element onClick={this._onClick}></Element>
  );
},
_onClick: function(e) {
  console.log(e);
}

Error message:
TypeError: e is undefined

Need to remove onClick on unit.js or add e
