Adding a button to a template UI

[napnap]

Hi!

So I want to add a button to a template, the template I'm talking about is this one:

This red area is this one :

	<Button name="LFGListApplicantMemberTemplate" virtual="true">
		<Size x="190" y="20"/>
		<Layers>
			<Layer level="ARTWORK">
				<FontString parentKey="Name" inherits="GameFontNormalSmall" justifyH="LEFT" text="NAME">
					<Size x="100" y="10"/>
					<Anchors>
						<Anchor point="LEFT" x="7" y="-1"/>
					</Anchors>
				</FontString>
				<FontString parentKey="ItemLevel" inherits="GameFontNormalSmall" justifyH="CENTER" text="529">
					<Anchors>
						<Anchor point="CENTER" relativeKey="$parent" relativePoint="LEFT" x="177" y="-1"/>
					</Anchors>
				</FontString>
			</Layer>
		</Layers>
		<Frames>
			<Frame parentKey="FriendIcon">
				<Size x="20" y="19"/>
				<Anchors>
					<Anchor point="LEFT" relativeKey="$parent.Name" relativePoint="RIGHT" x="0" y="0"/>
				</Anchors>
				<Layers>
					<Layer level="ARTWORK">
						<Texture parentKey="Icon" atlas="groupfinder-icon-friend" setAllPoints="true"/>
					</Layer>
				</Layers>
				<Scripts>
					<OnEnter>
						if ( self.relationship == "friend" ) then
							GameTooltip:SetOwner(self, "ANCHOR_RIGHT");
							GameTooltip:SetText(LFG_LIST_FRIEND, NORMAL_FONT_COLOR.r, NORMAL_FONT_COLOR.g, NORMAL_FONT_COLOR.b, 1, true);
							GameTooltip:Show();
						elseif ( self.relationship == "guild" ) then
							GameTooltip:SetOwner(self, "ANCHOR_RIGHT");
							GameTooltip:SetText(LFG_LIST_GUILD_MEMBER, NORMAL_FONT_COLOR.r, NORMAL_FONT_COLOR.g, NORMAL_FONT_COLOR.b, 1, true);
							GameTooltip:Show();
						else
							GameTooltip:Hide();
						end
					</OnEnter>
					<OnLeave function="GameTooltip_Hide"/>
				</Scripts>
			</Frame>
			<Button parentKey="RoleIcon1">
				<Size x="18" y="18"/>
				<Anchors>
					<Anchor point="LEFT" x="104" y="0"/>
				</Anchors>
				<NormalTexture/>
				<HighlightTexture alphaMode="ADD"/>
				<Scripts>
					<OnClick>
						PlaySound("igMainMenuOptionCheckBoxOn");
						C_LFGList.SetApplicantMemberRole(self:GetParent():GetParent().applicantID, self:GetParent().memberIdx, self.role);
					</OnClick>
				</Scripts>
			</Button>
			<Button parentKey="RoleIcon2">
				<Size x="18" y="18"/>
				<Anchors>
					<Anchor point="LEFT" relativeKey="$parent.RoleIcon1" relativePoint="RIGHT" x="1" y="0"/>
				</Anchors>
				<NormalTexture/>
				<HighlightTexture alphaMode="ADD"/>
				<Scripts>
					<OnClick>
						PlaySound("igMainMenuOptionCheckBoxOn");
						C_LFGList.SetApplicantMemberRole(self:GetParent():GetParent().applicantID, self:GetParent().memberIdx, self.role);
					</OnClick>
				</Scripts>
			</Button>
			<Button parentKey="RoleIcon3">
				<Size x="18" y="18"/>
				<Anchors>
					<Anchor point="LEFT" relativeKey="$parent.RoleIcon2" relativePoint="RIGHT" x="1" y="0"/>
				</Anchors>
				<NormalTexture/>
				<HighlightTexture alphaMode="ADD"/>
				<Scripts>
					<OnClick>
						PlaySound("igMainMenuOptionCheckBoxOn");
						C_LFGList.SetApplicantMemberRole(self:GetParent():GetParent().applicantID, self:GetParent().memberIdx, self.role);
					</OnClick>
				</Scripts>
			</Button>
		</Frames>
		<Scripts>
			<OnLoad>
				self:RegisterForClicks("RightButtonUp");
			</OnLoad>
			<OnClick>
				PlaySound("igMainMenuOptionCheckBoxOn");
				EasyMenu(LFGListUtil_GetApplicantMemberMenu(self:GetParent().applicantID, self.memberIdx), LFGListFrameDropDown, self, 60, -5, "MENU");
			</OnClick>
			<OnEnter function="LFGListApplicantMember_OnEnter"/>
			<OnLeave function="GameTooltip_Hide"/>
		</Scripts>
	</Button>

So my code looks like this:

<Ui>
    <Frame name="MyAddon" parent="LFGListApplicantMemberTemplate">
        <Size x="18" y="18"/>
        <Anchors>
            <Anchor point="TOPLEFT" relativePoint="TOPLEFT" x="4" y="-2"/>
        </Anchors>
        <Frames>
            <Button parentKey="MyAddonButton" inherits="UIMenuButtonStretchTemplate">
                <Size x="18" y="18"/>
                <Anchors>
                    <Anchor point="LEFT" relativeKey="$parent.Name" relativePoint="RIGHT" x="0" y="0"/>
                </Anchors>
                <HighlightTexture file="Interface\Buttons\UI-Common-MouseHilight" alphaMode="ADD"/>
            </Button>
        </Frames>
        <Scripts>
            <OnLoad>
                    self.MyAddonButton:SetText("Addon")
            </OnLoad>
        </Scripts>
    </Frame>
</Ui>

But nothing shows up. Any help please?
