Help with Slider template

[Likos]

Hello everyone!

I make simple template for Slider component in XML, such as:

<Slider name="SliderTemplate" orientation="HORIZONTAL" minValue="0" maxValue="1" valueStep="0.01" defaultValue="1" virtual="true">
		<Size x="200" y="16" />
		<Backdrop bgFile="Interface\Buttons\UI-SliderBar-Background" edgeFile="Interface\Buttons\UI-SliderBar-Border" tile="true">
			<EdgeSize>
				<AbsValue val="8"/>
			</EdgeSize>
			<TileSize>
				<AbsValue val="8"/>
			</TileSize>
			<BackgroundInsets>
				<AbsInset left="3" right="3" top="6" bottom="6"/>
			</BackgroundInsets>
		</Backdrop>
		<ThumbTexture file="Interface\Buttons\UI-SliderBar-Button-Horizontal">
			<Size>
				<AbsDimension x="32" y="32"/>
			</Size>
		</ThumbTexture>
		<Layers>
			<Layer level="ARTWORK">
				<FontString parentKey="curValue" name="$parentText" inherits="GameFontNormalSmall">
					<Anchors>
						<Anchor point="TOP" relativePoint="BOTTOM" x="0" y="-3" />
					</Anchors>
				</FontString>
				<FontString parentKey="minValue" inherits="GameFontNormalSmall" text="0">
					<Anchors>
						<Anchor point="TOPLEFT" relativePoint="BOTTOMLEFT" x="0" y="-3" />
					</Anchors>
				</FontString>
				<FontString parentKey="maxValue" inherits="GameFontNormalSmall" text="1">
					<Anchors>
						<Anchor point="TOPRIGHT" relativePoint="BOTTOMRIGHT" x="0" y="-3" />
					</Anchors>
				</FontString>
			</Layer>
		</Layers>
		<Scripts>
			<OnValueChanged>
				self.curValue:SetText(string.format("%.2f", value))
			</OnValueChanged>
		</Scripts>
	</Slider>

and using this template on a frame:

	<Frame name="TestFrame" inherits="BorderFrameTemplate" parent="UIParent">
		<Size x="300" y="200" />
		<Anchors>
			<Anchor point="CENTER" x="0" y="0" />
		</Anchors>
		<Frames>
			<Frame parentKey="Content" inherits="ContentFrameTemplate">
				<Anchors>
					<Anchor point="TOPLEFT" x="-5" y="2" />
					<Anchor point="BOTTOMRIGHT" x="5" y="-2" />
				</Anchors>
				<Frames>
					<Slider parentKey="Slider1" inherits="SliderTemplate">
						<Anchors>
							<Anchor point="CENTER" x="0" y="0" />
						</Anchors>
					</Slider>
				</Frames>
			</Frame>
		</Frames>
	</Frame>

In game i have my test frame, but inside this frame not showing slider. Also mouse have reaction on this slider, such as this slider have no textures.

What i do wrong?
