Sometimes data are not loaded from sqllite in Phonegap

I am using SQLLite in Phonegap. First time once app is initialized, I am inserting all records in different tables and then use it on different pages.

On different pages i have opened database and getting data from the sqllite. But my issue is that sometimes on page it is not loading data from sqllite but as soon as i press app back button or app's back button it loads data.

Here is my code on different page on device ready. Will you please guide

    var db;
    $(document).ready(function(){       
            document.addEventListener("deviceready", getdata, false);       
    });
   function getdata()
   {
     window.sqlitePlugin.openDatabase({name: "mayaa.db"});  
   }
