starnge behavior with multi-select combobox

[Anumeha]

I have a multi-select combobox defined on my page with checkboxes and radio buttons in the template.
I am observing a strange behavior with the dropdown.
To close the dropdown I have to click outside of the combo.
On my save I pop-up a radalert that says that data is saved.  If the user checks something in the combo and directly clicks save without clicking out anywhere on the form the pop-up takes two clicks to close. If I again repeat the same steps it increments another click till the time i refresh the page.

combo declaration:

<telerik:RadComboBox runat="server" ID="RadComboBoxParticipants" EnableLoadOnDemand="false"
                                Width="350px" OnPreRender="RadComboBoxParticipants_PreRender" AllowCustomText="true"
                                LoadingMessage="loading.." OnClientSelectedIndexChanging="OnClientSelectedIndexChanging" CloseDropDownOnBlur="true"
                                OnClientDropDownOpening="OnClientDropDownOpening" OnClientDropDownClosing="OnClientDropDownClosing"
                                OnClientBlur="OnClientBlur" OnItemDataBound="RadComboBoxParticipants_ItemDataBound">
                                <ItemTemplate>
                                    <table>
                                        <tr>
                                            <td>
                                                <asp:CheckBox ID="CheckBox1" runat="server" onclick="stopPropagation(event, this);"
                                                    ToolTip="Adds as option" />
                                            </td>
                                            <td>
                                                <asp:RadioButton ID="RadioButton1" runat="server" GroupName="Type" onclick="SetUniqueRadioButton();"
                                                    ToolTip="Sets as default" />
                                            </td>
                                            <td>
                                                <%# DataBinder.Eval(Container.DataItem,"FullName") %>
                                            </td>
                                        </tr>
                                    </table>
                                </ItemTemplate>
                                <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>
                            </telerik:RadComboBox>

Javascript:

var supressDropDownClosing = false;

            function OnClientDropDownClosing(sender, eventArgs) {
                eventArgs.set_cancel(supressDropDownClosing);
            }

            function OnClientSelectedIndexChanging(sender, eventArgs) {
                eventArgs.set_cancel(supressDropDownClosing);
            }

            function OnClientDropDownOpening(sender, eventArgs) {
                supressDropDownClosing = true;
            }

            function OnClientBlur(sender) {
                supressDropDownClosing = false;

                sender.toggleDropDown();
            }


            function stopPropagation(e, chk) {
                e.cancelBubble = true;
                if (e.stopPropagation) {
                    e.stopPropagation();
                }
}

This is very annoying for the client. Can you suggest something.
