成功api调用后没有进入reactjs中的函数？

Question

download() {
    let singlecontract = this.state.singlecontract; 
    let data = singlecontract.contract.html;
    let token = localStorage.getItem("accessToken");

    ContractAction._generatePDF(data,function(data) {
        var wnd = window.open("http://172.104.167.150:9082/contracts/downloadpdf?filename="+data.filename+"&access_token=" + token, "_blank");
        console.log(wnd);
        console.log(data);
    });   
}

成功后_generatePdf它没有进入无法在其他窗口中打开的功能。并且我无法控制值也没有进入函数
