Events on elements in Relative Layout not firing - xaml

Question

I am using Xamarin Forms and events on elements inside of a relative layout are not firing. I tried to register them in code behind as well and still not firing. I have -250 constraint on it because buttons were showing up on the bottom of the screen and it was the only way I could move them up.
Here is my xaml:
<StackLayout Orientation="Vertical">
<RelativeLayout>
<Grid Margin="0,0,10,0"
x:Name="grid"
RelativeLayout.YConstraint="{ConstraintExpression Type=RelativeToParent, Property=Y, Factor=0, Constant=10}"
RelativeLayout.XConstraint="{ConstraintExpression Type=RelativeToParent, Property=X, Factor=0, Constant=0}"
>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50*" />
<ColumnDefinition Width="50*" />
</Grid.ColumnDefinitions>
<Label Grid.Column="0"
Grid.Row="0"
Text="IP Address"
Margin="10,10,0,0"
HorizontalOptions="StartAndExpand"/>
<Entry Grid.Column="1"
Grid.Row="0"
x:Name="IPAddress"
Placeholder="IP"
WidthRequest="200"
Margin="0,0,10,0"
HorizontalOptions="EndAndExpand"/>
<Label Grid.Column="0"
Grid.Row="1"
Text="Port"
Margin="10,10,0,0"
MinimumWidthRequest="100"
HorizontalOptions="Start"/>
<Entry Grid.Column="1"
Grid.Row="1"
x:Name="Port"
Margin="0,0,10,0"

WidthRequest="200"
HorizontalOptions="End"/>
<Label Grid.Column="0"
Grid.Row="2"
Margin="10,10,0,0"
Text="User Name"
MinimumWidthRequest="100"
HorizontalOptions="Start"/>
<Entry Grid.Column="1"
Grid.Row="2"
x:Name="UserName"
Margin="0,0,10,0"
WidthRequest="200"

HorizontalOptions="End"/>
<Label Grid.Column="0"
Grid.Row="3"
Margin="10,10,0,0"
Text="Password"

<Entry Grid.Column="1"
Grid.Row="3"
x:Name="Password"
IsPassword="True"
Margin="0,0,10,0"
WidthRequest="200"
Placeholder="Password"
HorizontalOptions="End"/>
</Grid>
</RelativeLayout>
<RelativeLayout
IsEnabled="True">
<Button x:Name="SaveBtn"
IsEnabled="True"
WidthRequest="100"
RelativeLayout.YConstraint="{ConstraintExpression Type=RelativeToParent, Property=Y, Factor=0, Constant=-250}"
RelativeLayout.XConstraint="{ConstraintExpression Type=RelativeToParent, Property=X, Factor=0, Constant=30}"
Clicked="SaveBtn_Clicked"
BorderColor="Gray"
Text="Save"></Button>
<Button x:Name="ClearFavorites"
IsEnabled="True"
WidthRequest="120"
RelativeLayout.YConstraint="{ConstraintExpression Type=RelativeToParent, Property=Y, Factor=0, Constant=-250}"
RelativeLayout.XConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width, Factor=0.5, Constant=20}"
Clicked="ClearFavorites_Clicked"
BorderColor="Gray"
Text="Clear Favorites"></Button>
</RelativeLayout>
</StackLayout>

After discussion on chat this seems to work
<StackLayout Orientation="Vertical">
<RelativeLayout>
<Grid Margin="0,0,10,0"
x:Name="grid"
RelativeLayout.YConstraint="{ConstraintExpression Type=RelativeToParent, Property=Y, Factor=0, Constant=10}"
RelativeLayout.XConstraint="{ConstraintExpression Type=RelativeToParent, Property=X, Factor=0, Constant=0}"
