Color in symbols

Hello

    I'm trying to develop an application for soccer uniform coloring, and could color the svg. Only that will put many uniforms, then turned into symbol to put them in there. The button Next can navigate between models and coloring them, but when I click back models appear but unable to colored them or select them. I will put the code below to see if you can help me:

BUTTON BACK:

sym.getSymbol ("shirts") playReverse (.);

CODE SELECTING THE PARTIES:

EC.SVG.accessSVG (sym.getSymbol ('shirts'). $ ('C03')). Done (

function (svgDocument) {

// Add event listener

svgDocument.addEventListener ("select" function (event) {

// Remember selected part

sym.setVariable ("selectedPart" event.target);

// Show the id of the selected part in the textfield

sym $ ("selectedPartTxt") html (event.target.id)..;

});

});
