React JS warning

I am getting this warning when I run the below code.How can I remove the error?

Thank you.

Warning: Failed form propType: You provided a value prop to a form field without an onChange handler. This will render a read-only field. If the field should be mutable use defaultValue. Otherwise, set either onChange or readOnly. Check the render method of test.

var test = React.createClass({ getInitialState : function(){ return { number : 10, checked: [], selected : [] }; }, componentWillMount : function(){ }, moreAilment : function (){ var temp = this.state.number + 5; this.setState({number:temp}); }, handleChangechk: function (e){ const target = e.target; const value = target.type === 'checkbox' ? target.checked : target.value; const name = target.name; var checkedCopy = this.state.checked.slice(); var selectedCopy = this.state.selected.slice(); if(value===true) { checkedCopy[name] = true; selectedCopy [name] = name; } else { checkedCopy[name] = false; selectedCopy [name] = ''; } this.setState({ checked: checkedCopy, selected: selectedCopy }); }, render : function() { var ailmentsList = []; var selectedList= []; for (var i = 0; i < this.state.number; i++) { ailmentsList.push(<span ><input type="checkbox" checked={!!this.state.checked[i]} onChange={(e)=> {this.handleChangechk(e)}} /><span ></span><label> Asthma {i}</label></span>); if(this.state.selected[i]) { selectedList.push(this.state.selected[i]); } }; return( <div className> {selectedList} </div> ); } });
