KnockoutJS binding for the FlexGrid FlexGridFilter object.

The wjFlexGridFilter binding must be contained in a wjFlexGrid binding. For example:

<p>Here is a FlexGrid control with column filters:</p>
<div data-bind="wjFlexGrid: { itemsSource: data }">
    <div data-bind="wjFlexGridFilter: { filterColumns: ['country', 'amount']  }"></div>
 
    <div data-bind="wjFlexGridColumn: { 
        header: 'Country', 
        binding: 'country', 
        width: '*' }">
    </div>
    <div data-bind="wjFlexGridColumn: { 
        header: 'Date', 
        binding: 'date' }">
    </div>
    <div data-bind="wjFlexGridColumn: { 
        header: 'Revenue', 
        binding: 'amount', 
        format: 'n0' }">
    </div>
    <div data-bind="wjFlexGridColumn: { 
        header: 'Active', 
        binding: 'active' }">
    </div>
</div>

The wjFlexGridFilter binding supports all read-write properties and events of the FlexGridFilter class.
