I've used Appcontrol functionality in this purpose. You may follow the steps below:

1. Take one Web widget app & one Native service app.

2. Modify the main.js file of the widget app as below:
 

    var mainPage = document.getElementById("content-text"); 
	mainPage.onclick=click;
	mainPage.addEventListener('click', click);
	function click() {
		var obj = new tizen.ApplicationControlData("YOUR_WIDGET_APP_ID", ["Success"]); //you'll find the app id in config.xml file.
		var obj1 = new tizen.ApplicationControl("http://tizen.org/appcontrol/operation/service",
				null,
				null,
				null,
				[obj] 
		);
		//you'll find the service app id from the manifest file of service app.
		tizen.application.launchAppControl(obj1,
				"YOUR_SERVICE_APP_ID",
				function() {console.log("Launch Service succeeded"); },
				function(e) {console.log("Launch Service failed : " + e.message);}, null);

	}

3. In the service_app_control() function of the service app write the below code snippet.
 

char *operation;
	char *app_id;
	app_control_get_operation(app_control, &operation);

	if (!strcmp(operation, "http://tizen.org/appcontrol/operation/service")) {
		char *message;
		app_control_get_extra_data(app_control, "YOUR_WIDGET_APP_ID", &message);
		dlog_print(DLOG_DEBUG, "shaswati", " %s ", message);

	}

4. Install both of the applications. Now, you'll get to see a message whenever you click on the widget app text "Hello Widget". 

Hope it'll help.

You may use appControlReplyCallback in that case. Use the below code snippets.

In widget app (main.js):

var mainPage = document.getElementById("content-text"); 
    mainPage.onclick=click;
    mainPage.addEventListener('click', click);
	function click() {
		
		var appControlReplyCallback = {
				// callee sent a reply
				onsuccess: function(data) {

					document.getElementById("content-text").textContent = data[0].value[0];

				},
				// callee returned failure
				onfailure: function() {
					console.log('The launch application control failed');
				}
		}
		//document.getElementById("content-text").textContent = "My String";
		var obj = new tizen.ApplicationControlData("YOUR_WIDGET_APP_ID", ["Success"]);
		var obj1 = new tizen.ApplicationControl("http://tizen.org/appcontrol/operation/service",
				null,
				null,
				null,
				[obj] 
		);
		
		tizen.application.launchAppControl(obj1,
				"YOUR_SERVICE_APP_ID",
				function() {console.log("Launch Service succeeded"); },
				function(e) {console.log("Launch Service failed : " + e.message);}, appControlReplyCallback);

	}

 

In service app (service_app_control() function):

char *operation;
	app_control_get_operation(app_control, &operation);

	if (!strcmp(operation, "http://tizen.org/appcontrol/operation/service")) {
		char *message;
		app_control_get_extra_data(app_control, "YOUR_WIDGET_APP_ID", &message);
		dlog_print(DLOG_DEBUG, "shaswati", " %s ", message);
		app_control_h reply;
		app_control_create(&reply);
		app_control_add_extra_data(reply, APP_CONTROL_DATA_SELECTED, "Ok");
		app_control_reply_to_launch_request(reply, app_control, APP_CONTROL_RESULT_SUCCEEDED);
		app_control_destroy(reply);

	}
