Q:

Stop Modal Closing When 'OnTextChanged' Fires

I have an asp.net webform application and a user clicks a button, this then displays a modal with 3 fields in it.  I have added an OnTextChanged and AutoPostBack="true" as i have code behind that checks if the name entered in the first currently exists or not. but when ever i tab out the field my modal closed and i need it stay open.
I had a very simular situation with an accordion which i got working by Jquery and asp:HiddenField but i have tried altering the code to no avail.
Part HTML For Modal
<div class="form-group">
     <asp:Label ID="lblPlace" runat="server" Class="col-sm-3 control-label" Text="Place" AssociatedControlID="fldPlace" />
     <div class="col-sm-6">
          <asp:TextBox ID="fldPlace" runat="server" class="form-control" AutoPostBack="true" OnTextChanged="fldPlace_TextChanged" />
     </div>
</div>

The code i used for my accordion was
HTML
<asp:HiddenField runat="server" ID="toKeepRemoveAccordionOpen" />
<div class="form-group">        
     <asp:Label runat="server" AssociatedControlID="txtRemoveUser" CssClass="col-sm-offset-2 col-sm-3 control-label">Enter Name To Be Removed</asp:Label>
     <div class="col-sm-3">
          <asp:TextBox runat="server" ID="txtRemoveUser" CssClass="form-control" AutoPostBack="true" OnTextChanged="txtRemoveUser_TextChanged" />
     </div>
</div>

JQuery
$('document').ready(function ()
{
    var hdnFldId = '<%= toKeepRemoveAccordionOpen.ClientID %>';
    $("#MainContent_txtRemoveUser").on("blur", function ()
    {
        //Sets value of hidden field to show panel after postback
        $('#' + hdnFldId).val(true);
    });

    if ($('#' + hdnFldId).val() == 'true')
    {
        showPanel();
        // Resets the value
        $('#' + hdnFldId).val(false);
    }

    function showPanel()
    {
        if ($('#MainContent_txtRemoveUser').val() != '')
        {
            $('.panel-collapse').removeClass('collapse').addClass('in');
        }
    }
});

I did try the following JQuery
$('document').ready(function () {
            var hdnFldId = '<%= toKeepRemoveAccordionOpen.ClientID %>';
            $("#MainContent_fldPlace").on("blur", function () {
                //Sets value of hidden field to show panel after postback
                $('#' + hdnFldId).val(true);
            });

            if ($('#' + hdnFldId).val() == 'true') {
                showPanel();
                // Resets the value
                $('#' + hdnFldId).val(false);
            }

            function showPanel() {
                if ($('#MainContent_fldPlace').val() != '') {
                    //$('.modal').addClass('in');
                    $('.modal').removeClass('fade').addClass('fade in');
                }
            }
        });

The main class for a modal is modal fade and when its displayed it changes to modal fade in.

A:

Added the following to my aspx page
JQuery
function keepOpenSuggestPlaceModal()
{
    $('#placesModal').modal('show');
}

and added the following to my function call in my code behind
ScriptManager.RegisterStartupScript(this, this.GetType(), "Pop", "keepOpenSuggestPlaceModal();", true);
