how to call method in ios code from html response using uiwebview

Question

I am consuming html json data in my iOS app. HTML response has few div blocks with onClick methods. When I tap on these blocks I invoke some javascript code in web view, but I need also know about these events in my source code.

For example when I tap on web element and onClick is called I need to invoke some method in the code .

- (void)patientResponse:(UIWebView *)webView modeDict:(NSDictionary *)modeDict

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType 
{
    NSString *protocolPrefix = EVENT;

    NSString *urlStr = [[request URL].absoluteString substringFromIndex:protocolPrefix.length];

    urlStr = [urlStr stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

   NSError *jsonError;        

    NSDictionary *callInfo = [NSJSONSerialization
JSONObjectWithData:[urlStr dataUsingEncoding:NSUTF8StringEncoding]
options:kNilOptions error:&jsonError];    

    if([[callInfo valueForKey:@"acton"] isEqualToString:Set_id])

    [self patientResponse:webView modeDict:callInfo];

     return NO;  
    }

   - (void)patientResponse:(UIWebView *)webView modeDict:(NSDictionary *)modeDict
    {

    NSString *mode = [[modeDict valueForKey:@"params"] valueForKey:@"PatientName"];

    self.patientName = mode;

    NSLog(@"Patient name is:%@",self.patientName);

    }
