Experiencing difficulty decoding JSON output on jquarymobile's HTML page when making an Ajax request

After developing screens for my Android application using PhoneGap and jQuery Mobile, I have included the necessary JavaScript and CSS files in my HTML page:

 <link rel="stylesheet" href="css/jquery.mobile-1.3.1.css" />
 <script src="js/jquery-1.9.1.js" type="text/javascript"></script>
 <script src="js/jquery.mobile-1.3.1.js" type="text/javascript"></script>

The screens are working well, but now I need to bind data from a database to my screen. To achieve this, I have created web services that provide JSON outputs. Here is an example of one such JSON output:

[
 {"rest_id": 35, "rest_name": "Just 10"},
 {"rest_id": 36, "rest_name": "Egg Zone"},
 {"rest_id": 37, "rest_name": "Tandoor & Curries"},
 {"rest_id": 38, "rest_name": "China Bite"}
]

In my HTML page, I am attempting to parse this JSON data with the following script:

<script type="text/javascript">
        $.getJSON("MyURL", function( data ) {
            alert('success');
            /* My Logic for getting value from JSON output */
        });
     </script>

I'm encountering an issue where the alert message is not being displayed as expected. As a newcomer to these technologies, I would greatly appreciate any assistance on identifying where I may be going wrong.

Thank you all,

Although I am not well-versed in PhoneGap, it appears that in your script you have included code for retrieving data. It is essential to also include information regarding the request process, as Ajax revolves around requesting and receiving responses.

$.ajax({
  url : '${resourceURL}',
  data : data,//send Request 
  type: 'POST',
  dataType : "json",
  success : function(data) {
    // something my be alert(success)
  }
});

After reviewing your code snippet, it appears that the $.getJSON() function is not being called. To ensure it runs properly, you must invoke it within an event listener or upon DOM initialization.

$(document).ready(function(){
  $.getJSON("MyURL",
    function(data){
      alert('success');
      /* Implement logic to retrieve data from JSON response */
    }
  );
});

Try running this code snippet to verify if it functions as expected.
