从UIViewController调用JavaScript

Question

I know we can call Java script from UIWebView using stringByEvaluatingJavaScriptFromString but can I call Java Script from any other place other than a view controller?

I am displaying a UIPopover from a WebView I want to call js code from the popover to make changes in web page displayed below.

I tried calling a method in webview from popover's viewcontroller to call js, the methord is called but nothing happened

ViewController in popover

webView =[WebViewController alloc]init];
[webView methodToCallJs];

WebViewController

-(void)methodToCallJs
{

[_webView stringByEvaluatingJavaScriptFromString:@"sampleFunction()"];

}

Is there a way to do this ??
