this one helps. I am going to answer this myself :) Basically I decided that this was not the best way to handle my widget, so I used the widget factory boilerplate to sort out my issue. I modified my click event to this:
code :
$("#assets").on("click", ".glyphicon", function () {
    var $asset = $(this).parent(); // Get our asset element
    var $actionBar = $("#action-bar"); // Get the action bar
    var $selected = $("#selected-asset");// Get our selected asset counter

    var currentSelected = parseInt($selected.text()); // Get our current counter value
    var assetId = parseInt($asset.attr("id")); // Get the asset id
    var asset = $.grep(assets, function (obj) { // Find our asset from our array
        return obj.Id == assetId;

    if ($asset.hasClass("active")) { // If our asset is already selected, then we must unselect it
        $selected.text(currentSelected - 1); // First, decrease our counter
        tableWidget.tableBuilder("remove", asset[0]); // Then call our widget and remove the current asset from the table
        activeItems = $.grep(activeItems, function (obj) { // Repopulate our array of active assets
            return obj != asset;
        $asset.removeClass("active"); // And remove the active class from our element

        if (activeItems.length <= 0) { // Finally, if this is the only selected asset
            $actionBar.hide(); // Hide our actionbar
    } else { // Else, we are selecting an asset
        $selected.text(currentSelected + 1); // Increase our counter
        tableWidget.tableBuilder("add", asset[0]); // Add a row to our widget
        activeItems.push(asset[0]); // Add the asset to our array of active assets
        $asset.addClass("active"); // Add our active alss to our element

        $actionBar.show(); // And show our actionbar
var row = "<tr data-id=\"{Id}\"><td>{FileName}</td><td>{Metadata.FileSize}</td><td></td><td><button type=\"button\" class=\"close\" data-id=\"{Id}\" aria-hidden=\"true\">&times;</button></td></tr>"
var tableWidget;

$(function () {
    tableWidget = $("#assets-table").tableBuilder({
        rowTemplate: row

app.catalog = new Browser.Catalog();
initialize: function (options) {
    app.catalog = new Browser.Catalog();

To fix this issue I am building a Wordpress plugin based on the Wordpress Plugin Boilerplate (Object-Orientated Programming) and I am facing a difficulty when calling the function displaying my plugin admin page in my custom admin dashboard menu. , Try to put your display_admin_page() method outside the class
code :
function display_admin_page() {

    echo '<div class="wrap">';
    echo '<h2>Welcome To WordPets</h2>';
    echo '<p>This is the custom admin page created from the custom admin menu.</p>';

    echo '</div><!-- end .wrap -->';
    echo '<div class="clear"></div>';

To fix this issue Hi I have a terrible problem. I generated the code plug on the page: http://wppb.me/
code :
        register_activation_hook( __FILE__,array( 'My_Activator', 'activate' )  );
class My_Activator {
    public static function activate() {
global $wpdb;
        global $jal_db_version;
        $table_name = $wpdb->prefix . 'fnotice';
        $charset_collate = $wpdb->get_charset_collate();

        $sql = "CREATE TABLE $table_name (
                    id INT NOT NULL AUTO_INCREMENT,
                    msg varchar(500) NOT NULL,
                    time DATETIME NOT NULL,
                    type varchar(350) NOT NULL,
                    link varchar(350) NOT NULL,
                    status ENUM('0', '1') NOT NULL default '1',
                    PRIMARY KEY (id) )";

        require_once( ABSPATH . 'wp-admin/includes/upgrade.php' );
        dbDelta( $sql );

        add_option( 'jal_db_version', $jal_db_version );


Refresh permissions from in-memory cache with ASP.NET Boilerplate

Refresh permissions from in-memory cache with ASP.NET Boilerplate

should help you out When I explicitly set a permission for a user in the database by running a SQL update script, the particular permission with the latest grant is not reflecting in the system. However when I recycle the IIS process or rebuild the solution, it only then seems to update. , You can inject ICacheManager and clear the cache:
code :
public void ForceRefresh()
 // _cacheManager.GetRolePermissionCache().Clear();
