Populating GridVIewComboBox with Enum

I have a grid such that when I load the grid it's populated with "Active Records". Every column populates properly except the enum column, the enum colkumn is blank. The combobox I can click into and it is populated with the enums.

If I can get some help to setting the enum to display correctly please. 

<telerik:GridViewComboBoxColumn Width="100" 
                                DataMemberBinding="{Binding Occurence}"                         
                                ItemsSource="{Binding Source={x:Type accounts:Insurance+Occurences}, Converter={StaticResource EnumToArrayConverter}}">
</telerik:GridViewComboBoxColumn>
<telerik:GridViewDataColumn Header="Rate" DataMemberBinding="{Binding Rate, StringFormat='#,##0.#0'}">
    <telerik:GridViewDataColumn.CellEditTemplate>
        <DataTemplate>
            <TextBox Text="{Binding Rate, Mode=TwoWay, StringFormat='#,##0.#0', UpdateSourceTrigger=PropertyChanged}" HorizontalContentAlignment="Right" />
        </DataTemplate>
    </telerik:GridViewDataColumn.CellEditTemplate>
</telerik:GridViewDataColumn>


<ObjectDataProvider x:Key="MyEnumDataProvider" MethodName="GetValues" ObjectType="{x:Type System:Enum}">
    <ObjectDataProvider.MethodParameters>
        <x:Type TypeName="accounts:InsuranceTypes"></x:Type>
    </ObjectDataProvider.MethodParameters>
</ObjectDataProvider>

EnumToArrayConverter is from WPF: How to populate combobox with enum in Xaml

The Rates column populates but the enum column remains empty.

Following code will solve it using object data provider

<ObjectDataProvider MethodName="GetValues"
                ObjectType="{x:Type sys:Enum}"
                x:Key="EnumDataProvider">
<ObjectDataProvider.MethodParameters>
    <x:Type TypeName="local:SomeENUM" />
</ObjectDataProvider.MethodParameters>

then use data column and override its template to have combobox in it and bind combo box like this 

<telerik:GridViewDataColumn.CellTemplate>
            <DataTemplate>
                <ComboBox ItemsSource="{Binding Source={StaticResource EnumDataProvider}}"
      SelectedItem="{Binding selectedEnum}"/>
            </DataTemplate>
</telerik:GridViewDataColumn.CellTemplate>
