select all in react-native-icon-checkbox

I install this library http://ift.tt/25Fq985 and it works very well with me now I need to use select all checkbox but the problem faced me is how to make all of the checkboxes be checked or unchecked

I try this in the single check box and it works fine

 <QCCheckboxVIcon onPressed={(isChecked) => this.selectCheckedChanged(isChecked, item.BasketId, item.Amount)}
                                    freez={freez} selected={ this.state.selectAll }
                                    ref={(c) => this._check = c} />

this is the select all button

 <QCCheckboxVIcon onPressed={(isChecked) => this.togleSelectAll(isChecked,data)}
                                            selected={ this.state.selectedCheckboxs == data.length}
                                            freez={freez} />

and this is the function I used

 togleSelectAll(isChecked,data) {
       let itms = [];
        if(isChecked) {
            for(var i=0; i < data.length; i++) {
              alert( data[i].BasketId+' '+  data[i].Amount)

              selectedItems.push({BasketId: data[i].BasketId, Amount: data[i].Amount});                
            selectedItems.map((itm, index) => {
                itms.push(itm.BasketId);
            });
            this.props.onSelectedItemsChanged(itms);

            freez = true;
            let total = 0;
            selectedItems.map((itm, index) => {
                total += itm.Amount;
            });
            this.setState({
                totalAmount: total,
                selectedCheckboxs: this.state.selectedCheckboxs ,
            });
            setTimeout(() => {freez = false;}, 3000);
              }                
        } }

it works great in getting total and know items but the problem is it didn't highlight the children checkboxes as this image
