silverlight imagebutton usercontrol

i am only starting out silverlight (2 rc0) cant seem following work. i wish emanate rudimentary settlement symbol user control.

my xaml user control follows:

 <button>
        <button.template>   
            <controltemplate>
                <image source="{templatebinding imagesource}" width="{templatebinding width}" height="{templatebinding height}" />
            </controltemplate>
        </button.template>
    </button>

the formula behind follows:

public biased category imagebuttonusercontrol : usercontrol
    {
        open imagebuttonusercontrol()
        {
            initializecomponent();
        }

        open settlement source
        {
            { relapse base.getvalue(sourceproperty) image; }
            set { base.setvalue(sourceproperty, value); }
        }
        open stationary readonly dependencyproperty sourceproperty = 
            dependencyproperty.register("sourceproperty", typeof(image), typeof(imagebuttonusercontrol),null);
    }

i wish means boldly emanate imagebuttons things enclosing wrappanel:
assume have an settlement named image already:

imagebuttonusercontrol imagebutton = new imagebuttonusercontrol();
imagebutton.source = image;
this.thumbnailstackpanel.children.add(imagebutton);

what i need settlement display? i'm presumption i need something datacontext, nonetheless i'm definitely certain where.
